Ryanair: 199-seat aircraft would hit capacity 'sweet spot'

Ryanair chief financial officer and deputy CEO Howard Millar would snap up a 199-seater aircraft because it hits a "sweet spot" in terms of staffing levels.
"The largest aircraft that we would be interested in is 199 seats," said Millar, speaking to ATI at Ryanair's Dublin headquarters. "That would mean that we could go up 10 seats without adding any more cabin crew. Our sweet spot is a 199-passenger aircraft,"
He says this would make sense in terms of incremental costs because when an aircraft goes over the 200-seat mark, another member of cabin crew is required.
"We think we could still do our turnarounds in 25 minutes with 199 passengers. If someone made this aircraft, we would operate it," says Millar.
Today Boeing offers the 737-800 and -900, both of which are limited to a maximum of 189 seats, while the Airbus A320 carries a maximum of 180 passengers.
Boeing's most recent offering - the 737-900ER - is available with additional passenger doors and is capable of accommodating up to 215 passengers. However, Millar rejects this as an option because it would be inefficient to operate the 737-900ER below its maximum capacity.

Concorde through the years & its Trails


A model of planned supersonic airliner Concorde went on show at Farnborough in 1962

Later that year, French Ambassador Geoffroy de Courcel (left) & the British Minister of Aviation, Julian Amery, signed the Anglo-French supersonic airliner agreement - and Concorde was born.




The airliner was constructed in both France & Britain. Here, a wooden mock-up of Concorde can be seen at the factory in Filton, Bristol.


 On the other side of channel, Concorde prototype 001 can be seen under construction at the Sud Aviation factory in St Martin-Toulouse in 1966.


In March of that year, a section of Fuselage was wheeled out of the hangar at Filton for testing.



Concorde's official roll-out ceremony in Toulouse in 1967 was attended by Britain's Minister of Technology Tony Benn & the French Minister of Transport, Jean Chamant.



Employees of BOAC crowded around to get a close look at the Prototype in 1968.


On 2 march 1969, Andre Turcat piloted the first flight of the French prototype Concorde 001 at Toulouse-Blagnac.



The first British Concorde, 002, took to the air on 9 April 1969, a month after its French counterpart.



In 1972, aircraft engineer & industrialist Sir George Edwards presented BOAC chairman Keith Granville with a silver model of a Concorde airliner after BOAC signed a contract to buy five of the aircraft.



Thirty-five passengers waved goodbye before departing from Heathrow Ariport on Concorde's first public flight in 1975.




Following the lifting of a ban on Concorde flights to New york, Capt Brian Walpole smiles from the cockpit on 22 NOV 1977, having just flown in from london.


Concorde's speed and expense quickly linked it in the public imagination to national leaders, top executives, rock & Film stars - and royalty. Pictured is the Queen on board in 1977.




Even the Pope traveled on Concorde. Here John Paul II waves to well-wishers as he disembarks at Lusaka airport in 1989.




In 1995, Concorde set a new round-the-world speed record. The supersonic jet made the trip in 31hrs 27 mins and 49 secs, passing through three sunrises.




The beginning of the end for Concorde came at Paris Charles de Gaulle airpot on 25 July 2000. The crash killed 113 people.




Following the crash, BA & Air France made a joint announcement on the Jet's retirement. Many of the planes ended up in museums. This Air France Concorde took a novel route to get to its new home in southern Germany.


For those who saw it, Concorde will always be remembered for its unique shape & the sound of its Rolls-Royce engines.


Q&A: Concorde crash trial

The trial concerning the only crash ever to involve a Concorde supersonic airliner is taking place in Pontoise, near Paris. Continental, the US airline, and five individuals face charges of manslaughter after 113 people died when an Air France Concorde crashed in July 2000.
What happened?
Concorde flight 4590 crashed in the town of Gonesse shortly after taking off in flames from Charles de Gaulle airport outside Paris on 25 July 2000.
The stricken Air France plane hit a hotel, killing all 109 people on board as well as four people on the ground.
Most of the passengers were German tourists heading to New York to join a luxury cruise to the Caribbean. Nine French crew members also died.
What caused the crash?
The official accident report into the crash said a piece of metal fell off a plane run by US airline Continental, which had taken off from Paris Charles de Gaulle airport just before the doomed Concorde was to take off.
The supersonic airliner hit the 43cm (17in) titanium strip and one of the plane's tyres burst, causing rubber to fly up and rupture a fuel tank, the report said.
Leaking kerosene then ignited, causing the fire.
The report was published in December 2004.
Who was charged?
In 2008 a French public prosecutor asked judges to bring manslaughter charges against Houston-based Continental Airlines, which denies responsibility.
Five individuals are also being prosecuted:
  • John Taylor, the Continental mechanic who allegedly fitted the metal strip to the DC-10
  • Stanley Ford, a Continental maintenance official
  • Jacques Herubel, Concorde's former chief engineer
  • Henri Perrier, a former head of the Concorde division at Aerospatiale, now part of the aerospace company EADS
  • Claude Frantzen, a former member of France's civil aviation watchdog
They deny the charges.
Only some of the victims' families will be represented at the hearings, as many took compensation from Air France after the crash in return for not taking legal action.
What is the case for the defence?
Lawyers for Continental say they can prove the Concorde was not airworthy, and that it caught fire before it struck the titanium strip.
Olivier Metzner, a lawyer for Continental, said: "We are going to fight it and establish that the Concorde caught fire eight seconds before this scrap of metal met with the Concorde - so about 700m (2,300ft) before."
This is denied by Air France, which is not facing charges.
The trial is expected to last four months.
Successful prosecution would result in a maximum fine of 375,000 euros (£330,000) for Continental, and prison sentences of up to five years as well as fines of up to 75,000 euros for the individuals charged.
Why has the case taken so long to come to trial?
The official report into the crash was published in December 2004, and French authorities began a criminal investigation of Continental in March 2005.
Following that investigation Bernard Farret, a deputy prosecutor in Pontoise, outside Paris, asked judges to bring manslaughter charges against the defendants in March 2008.
What happened to Concorde after the crash?
Some argue Concorde's reputation never fully recovered after the disaster - the only crash ever to involve one of the supersonic airliners.
Air France and British Airways retired their Concorde fleets in October 2003, ending three decades of supersonic travel, when the final commercial flights from New York landed at Heathrow.
What will the trial achieve?
Some critics have suggested holding a trial a decade after the event serves no useful purpose.
After the crash, most of the victims' families agreed to take no legal action in return for undisclosed levels of compensation from Air France, EADS, Continental and the tyre-maker, Goodyear.
Concorde has since been retired, so the case is more about the reputation of the two companies involved - Continental and Air France.
The US-based Flight Safety Foundation says such cases are harmful as they discourage industry officials from sharing important safety information which could be used in future court cases.
Where can I find more about this on the web?
You can check the BBC News story for the latest developments in the trial, or read a transcript of the Concorde crew's last words.
You can also read the official report into the crash.



End of an era for Concorde
Concorde at Heathrow
Concorde had a grandstand finish at Heathrow
Concorde has completed its last commercial passenger flight, ending three decades of supersonic travel. Three flights landed at Heathrow airport within five minutes of each other, watched by thousands of onlookers on Friday afternoon.
The last transatlantic flight carried 100 celebrities from New York and touched down at 1605 BST.
On disembarking, actress Joan Collins said there were "cheers and tears" among the passengers when the plane landed.
Minutes before the transatlantic trip touched down, competition winners landed on a flight from Edinburgh and a third completed its trip for invited guests around the Bay of Biscay.
British Airways decided to retire the famous aircraft after 27 years because it was no longer profitable.
Airport operator BAA built a 1,000-seat grandstand for spectators and many arrived at Heathrow hours before Concorde was due to arrive.

John Cowburn, 39, from Basingstoke, equipped with a ladder to get a good view, has seen it in action 25 times. He said: "Today is a very sad day but we must make the most of it. Concorde is potentially the most special thing man has ever built."
There was also an emotional goodbye on the other side of the Atlantic.
Water cannon sprayed the Concorde with jets of red, white and blue water to evoke the colours of the British, American and French flags in a symbolic farewell on the runway at John F Kennedy airport.
Before entering the Concorde cockpit for the last time, Captain Mike Bannister said he was "proud and privileged" to fly the plane back from New York.

"What we have tried to do is to make the retirement of Concorde a celebration - something that both the public and the airline can look back at with pride.

FINAL IMAGES
Spectators at Howard Beach
"When I power the engines for the last time at Heathrow I shall be thinking of all the people in BA who've kept this plane flying successfully for 27 years," he said. The New York flight left at at 1235 BST, another left Edinburgh at 1420 BST and a third began a loop of the Bay of Biscay a few minutes later.
Earlier, the first of the planes departed from Heathrow at 1035 BST for a flight to Edinburgh, where it landed at noon before leaving again for its final journey.
Actress Joan Collins, who has flown Concorde about 10 times and is on board the flight from New York, said the end of the era was "tragic".
"The first time I ever flew Concorde was a bit of a white knuckle ride. I am more used to it now, it's so wonderful to make the journey in three and a half hours," she said as she boarded the plane.
'Speed freak'
British broadcaster and frequent flyer Sir David Frost said he had lost count of the number of times he had been on Concorde - "somewhere between 300 and 500, I think."

PASSENGER LIST

The passenger list for Concorde's final flight from New York includes:

Broadcaster Sir David Frost
Actress Joan Collins
Politician Tony Benn
Former US model Christie Brinkley
Formula 1 chief Bernie Ecclestone
Stock exchange chairman Chris Gibson-Smith
British Airways chairman Lord Marshall

Model Jodie Kidd, checking into the flight, said: "I always really love the rush of takeoff. I am just a speed freak."

British Airways chief executive officer Rod Eddington said there was a "mixture of sadness and celebration" about the retirement.
"It is a wonderful plane, an icon, but its time has come. It's an old plane - it doesn't look it - but it was designed in the 50s and built in the 60s," he told BBC One's Breakfast.
In 1956, Britain and France began working separately on an aircraft that would fly at twice the speed of sound.
BA and Air France made a joint announcement on the retirement in April and the French Concorde's final flight was in May.
Concorde never recovered after a horrific crash near Paris Charles de Gaulle airport three years ago, in which 113 people died.

business aircraft census 2010 - Flight Global

http://www.flightglobal.com/articles/2010/10/11/348248/rough-but-ready-business-aircraft-census-2010.html

It has been a tough year for the world's business aviation industry. Unable to break free from the worst economic downturn for 70 years, this beleaguered aerospace sector has battled falling aircraft demand, a bloated used aircraft inventory and an unprecedented squeeze on bank lending. These factors have forced manufacturers to make drastic cuts in aircraft production and massive job losses across their plants.
This gloom is illustrated by the most recent General Aviation Manufacturers Association statistics, which recorded a 10% fall in business aircraft shipments for the first six months of 2010 compared with the previous year. The outlook for the next 12 months is equally bleak, says the Teal Group's vice-president, analysis Richard Aboulafia. "We are in a three year downturn and 2011 is the trough," he says.

Flight International's 2010 business aircraft census - compiled using Flightglobal's ACAS business aviation database - reflects the industry's weak performance in the 12 months from 31 August 2009. It reveals the world's active turbine corporate aircraft fleet has climbed by less than 3% to 28,614 jets and turboprops, compared with 27,409 aircraft in 2009.
The business jet fleet has grown by a modest 4% since August 2009, yet the turboprop fleet has remained almost stagnant throughout the census period, rising only 0.3% from 10,725 aircraft to 10,765 units. While the quest for fuel-efficient and understated transport continues, demand for most of these niche aircraft types has fallen significantly over the past 12 months.


"The impact of the economic recession has been felt most acutely at the lighter end of the business jet spectrum," Aboulafia admits.
"Deliveries in the bottom half of the market declined in 2009 by a remarkable 42.8% by value [excluding very light jets]," he says . "This represents the worst decline of any aerospace market in the present downturn. It was worse than the decline suffered by the majority of world economic markets," he says.
Of course, the lower end of the market has traditionally been dependent on third party finance, which has become increasingly hard to secure since the financial meltdown.
Even banks still willing to lend have tightened their criteria, forcing many potential buyers to delay, postpone or cancel an aircraft purchase. "The numbers of banks have dwindled since 2008 and gone are the days where customers can get a loan without the banks asking searching questions," says Paul Washington, aviation finance manager for SG Equipment Finance.
The lighter end of the marker has also had a greater exposure to the fractional ownership fall out. This sector - once the darling of the business aircraft industry - accounted for a large proportion of light jet sales. When the crisis hit hundreds of owners were forced to sell their shares. NetJets - the largest fractional programme - bought back 500 aircraft alone in the past 18 months - many of which have yet to be resold.
For the makers of light-cabin aircraft, the past 12 months have been brutal.






The major players - Bombardier, Cessna and Hawker Beechcraft have bore the brunt of the painful fallout - particularly in North America, where their exposure is greatest. Cessna in September was forced to lay off a further 700 workers - mainly at its Wichita facility - on top of the 8,000 job cuts that have already been made since the downturn hit in 2008. The reason for these losses is evident. In the first six months the airframer delivered only 130 jets and turboprops compared with 194 during the same period in 2009.

Profitability no longer the spur
Demand for business aircraft has long been indelibly linked to corporate profitability - when companies made money, manufacturers sold more aircraft. In the current climate these ties have been loosened.
Many economies are emerging slowly from the depths of recession and corporate profits are being restored to pre-crisis levels, but the health of the business aircraft manufacturing industry remains fragile.
According to the US Bureau of Economic Analysis, second quarter 2010 numbers reveal that US corporate profits are running at an annualised rate of $1.693 trillion since 2001. "It is impossible to state empirically that one type of profit is more conducive to business jet demand than any other," says Richard Aboulafia, senior analyst with US consultancy the Teal Group. "It is notable that manufacturing profits have made the strongest leap of all the business sectors."
According to the BEA, US manufacturing profits leaped from $53 billion in 2001 and $48 billion in 2002 to $305 billion in 2006 and $271 billion in 2007. The second quarter numbers have not yet been published, but the first quarter of 2010 saw manufacturing sector results that were nearly in line with the 2006-07 peak.
"Since aircraft delivery rate changes typically trail corporate profits changes by 12-24 months, the good news is that we might see a production increase as early as mid-2011. The bad news is that there are serious complications to this rosy outlook," Aboulafia says. "Corporate profits do not resemble the broader economy. Unemployment is still quite high and the economies of the developed world are only growing at an anaemic pace." Most of all, he says, key equities markets have not recovered in line with corporate profits.
Healthy profits are not necessarily a sign of the economy's sustainable health, he adds. "Companies are making money because they have slashed costs. The modest increase in consumer and business demand over the past year has benefited increasingly lean and productive companies."

The decline was attributable entirely to a slump in Citation business jet sales as the delivery tally for Caravan single-engined turboprops rose during the same period from 41 to 56 aircraft. The utility aircraft has been a welcome fillip for Cessna as its appeal has been recognised across all aerospace sectors, including maritime patrol, search and rescue, where budgets are less exposed to economic cycles.
Cessna continues to dominate the business aircraft arena, however, in terms of total inventory, with 5,823 business jets and 545 turboprops recorded in this year's census. The largest gains were made by Mustang entry-level jet. The Mustang fleet climbed by 115 aircraft to 315 over the census period, despite supplier issues earlier in the year. The introduction this year of the CJ4 to the Citation line-up should help to boost Citation numbers further.
Cessna's dominance of the bottom half of the business aircraft market will however, keep it exposed to the economic cycles for some time to come. The airframer is keen to re-enter the large-cabin aircraft arena and has not ruled out relaunching its Columbus business jet when market conditions are right and offering a high- speed competitor to the Gulfstream G650.
Clean- sheet designs are not on the cards for Hawker Beechcraft. It has concentrated on upgrading its product line with its latest model - the entry-level Premier II - set to enter service in 2013. Like Cessna, Hawker Beechcraft has cut its workforce drastically over the past year as demand for its aircraft has fallen. The manufacturer's business jet fleet has climbed by 3% to 2,251 aircraft, including a further 29 950XPs, eight 750s, 13 Premier IA and 39 Hawker 4000s - an 180% increase over last year's total. However, its turboprop fleet has fallen by 59 aircraft since the last census due to the removal from the report of over 160 ageing King Air twins.
The 46-year-old King Air retains its unrivalled dominance of the turboprop market with a fleet of nearly 5,500 aircraft. This ubiquitous type is the backbone of the company's manufacturing empire, representing more than half the world's twin-turboprop fleet and including 610 350 series, 81 B200GTs, 31 350s, 38 B200GTs, 65 C90GT/Is and 184 C90GTs. The latter figure includes the latest GTX, which entered service earlier this year, replacing the three-year-old C90GTi in service.
Bombardier's diverse product line has helped to lessen the impact of the economic crisis on its lower-end business jets. The Canadian airframer grew its inventory over the census period from 3,531 to 3,606. The light/superlight Learjet 40XR and 45XR tallies have climbed by eight and 19 respectively and the midsize Learjet 60XR by 19, as listed by ACAS. Further up the product line the annual tallies increase. The Canadian airframer will hope that the new all-composite Learjet 85 will dominate the midsize cabin arena when it enters service in 2013.




ALL THE BLANKS ARE WITH IMAGES - WHICH ARE PASTED ABOVE

It has already held this accolade in the super-midsize arena with its Challenger 300, which has seen its fleet climb by 37 aircraft to 280 jets since the last census. Other members of the Challenger family have also made impressive gains - the Challenger 850 by 26 and the Challenger 605 by 40 aircraft, bringing Bombardier's total fleet to 122 large-cabin types. At the top of its range, the Global 5000 has seen fleet numbers climb by 18 aircraft to 88 and the XRS by 38 aircraft to 126 of the long-range types.
Bombardier has established itself as a major player at the top of the business jet market. In September it received the thumbs-up from its directors to launch at the NBAA new members of its Global family. The line-up is expected to include a challenger to Gulfstream's ultra-long-range, high-speed G650.
Gulfstream, however, is going full steam ahead with the ultra-long-range aircraft, for which it has more than 200 orders ahead of its service entry next year. The Savannah Georgia-based airframer has seen its in-service fleet jump by around 5% to 1,907 business jets.


Despite a cut in overall production numbers this year, Gulfstream has seen its in-service business jet fleet jump by 5% from 1,817 to1,907 including a 25% increase in the long-range G550 inventory to 250 aircraft, a 20% increase in the large-cabin 450 fleet and a 7% increase in the G200 tally, to 214 aircraft. The super-midsize aircraft is to be replaced by the G250 next year.
Dassault plans to launch a super-midsize aircraft rival to the G250, Challenger 300 and Hawker 4000, but is tight-lipped about a possible launch date. The French airframer's dominance in the high end of the business jet market has helped it to ride the economic storm - although the journey has been bumpy. The inventory of business jets has nudged up by 78 to 1,751 Falcons, including 85 7X jets - more than double last year's tally of 37 - and 44 2000LX jets, making its census debut this year. Service entry of its long-legged stablemate the 900LX is imminent and the winglet-equipped large-cabin jet will make its census debut next year.
Embraer again has the largest fleet gains, recording a 160% increase in its global inventory to 363 business jets. The jump is attributable to the production ramp-up of the Phenom 100, as the light jet fleet has leapt from 24 to 153 in the census period. The larger light-cabin Phenom 300 makes its census debut with 20 aircraft. Two more Lineage 1000s have been added since the last report and the Legacy 600 - which has had its production halved this year - has nudged ahead by 17 aircraft.
The new longer-range Legacy 650 is expected to enter service later this year as a rival to well-established designs, including the G350, 2000LX and Challenger 605. Meanwhile, Embraer is maintaining schedules for its new mid-range product offerings in the hope that the market will be in recovery. The larger Legacy 500 - the fifth business jet in its portfolio - is earmarked for service entry in the second half of 2012, a year ahead of its mid-light Legacy 450.
At the top end of the business jet market, Airbus and Boeing have continued to expand their fleets of VIP-configured airliners, but the past 12 months have bought mixed results. Boeing's BBJ, BBJ2 and BBJ3 inventory has climbed by a modest five aircraft and its 777 tally by two. The cargo-door equipped BBJC makes its census debut with a single unit.
Although deliveries are expected to pick up this year, market conditions have been tough for Boeing, which suffered cancellations and deferrals from its high-end customers. In contrast, Airbus, which has had few deferrals and cancellations, has seen its tally increase by 20 to 107 corporate airliners. The A318 Elite fleet climbed by 40% to 12, the single-aisle A319 Airbus Corporate Jetliners fleet by eight and the twin-aisle A340 fleet by two. Airbus is increasing its marketing activity within Asia Pacific, notably in China, where it forecasts a demand for around five 15-plus-seat VIP aircraft a year.
GLOBAL MARKETS
Airframers' reliance on the global marketplace to boost their orderbooks is as prevalent now as ever. Without exception, the markets outside North American make up more than 50% of orders for the manufacturers and it is not hard to see why this focus has shifted. The painful economic downturn in North America and the USA in particular has wreaked havoc on the continent's business aircraft inventory over the past 12 months.
ACAS lists the installed base has nudging forward by 1.9% during the census period - the slowest growth of any of the world regions - as individuals and companies tighten their belts and wait for the fragile economy to grow. The USA is home to the largest installed base of business jets and turboprops with 11,490 and 7,095, respectively, and is unlikely to be toppled from this number one spot any time soon.


This cannot be said for Europe, however. Still home to the second largest concentration of business aircraft, the continent's exposure to the economic fall-out has had an effect on the this year's tally. ACAS reveals that the fleet has grown by just over 3% to 3,835 business jets and turboprops. The bulk of this growth is recorded in Russia and Austria - with gains of 13 and 26 business jets respectively.
Portugal - home to NetJets Europe - saw its tally fall by over 25 aircraft since the last census as the fractional provider removed unwanted mainly light-cabin business jets from its fleet due to changing customer circumstances.
Snapping at Europe's heels for second place is Latin America. This thriving region has seen its installed base climb in the census period by 356 jets and turboprops to 3,331 aircraft, reveals ACAS. This 12% climb is almost entirely due to the bullish economies of Argentina, Brazil and Mexico, which is driving demand for these flexible forms of transport. Argentina saw its tally leap by 20% to 110 jets and 112 turboprops. Brazil - home to the largest installed base of business aircraft in Latin America - saw its fleet climb by 104 jets and 66 turboprops. Meanwhile, Mexico - which houses the continent's largest business jet fleet - saw its tally climb by 55 to 606 jets and 271 turboprops.
The Pacific Rim has also made strides over the past 12 months. ACAS lists the fleet rise as more than 11%, to 501 jets and 416 turboprops. Australia has emerged over the past 12 months as a dominant player in the region, making gains of 11 jets and 11 turboprops respectively bringing its total fleet to 333 aircraft.
China has made the largest gains, recording a 20% increase in its business jet tally to 142 aircraft. The world's airframers expect the market to grow at an even greater pace as the country's economy continues to boom, regulations become more relaxed and the military loosens its grip on the nation's airspace.
The Middle Eastern fleet has also progressed over the past 12 month with much of the growth coming from sales of large-cabin business jets and airliners. ACAS data reveals a climb of 44 jets and six turboprops, with the major gains recorded in the United Arab Emirates - 102 to 118 jets and turboprops - and Saudi Arabia, with 16 jets and six turboprops.
The past 12 months have not been entirely smooth, however, says ExecuJet Middle East managing director Mike Berry. "The downturn impacted us later than most other economies. Aircraft sales have fallen and the charter and management business has become increasingly competitive as there are fewer aircraft available. But it will always be a prominent market for business aviation due to the high volumes of high-net-worth individuals."
LONG-RANGE AIRCRAFT ARE SWEET SPOT
Used aircraft inventories remain stubbornly high. Around 13% of the global business aircraft fleet is for sale - well above the industry average of around 10%. "As a rule of thumb, when the inventory dips below this mark, it is typically a sellers' market and when it goes above 10% it is a buyers' market," says Oliver Stone, executive director, Business Air International.
The older-generation types are providing harder to shift - notably the light-cabin Cessna Citation II and Bombardier Learjet 35A. These aircraft types are listed in the Flightglobal ACAS database as the top two most common business jets, with fleets of 579 and 374 aircraft respectively.
"The Citation II is the bread and butter of the business aviation industry," says JetBrokers Europe chief executive Tim Barber, "but there is 25% of the global stock on the market today - enough stock to fulfil the current sales demand for the next two years."
Even overhauling the engine to extend the lifespan of the aircraft has been ruled out, says Barber, as this can cost around half the price of the aircraft. "A used CII, for example, is valued at around $1.2 million, but the overhaul will cost over $600,000."
Consequently, there has been "a flurry of activity" on the used engine market as owners trade powerplants in an effort to enhance the life and appeal of their aircraft.
"There is still significant supply of these aircraft. So much so that at the current rate of sales there is enough inventory for the next two and a half years," says Barber.
To control the size and cost of their used aircraft inventories, some airframers try to keep track of each aircraft that is put up for sale and offer sellers incentives to boost the aircraft's appeal to a future buyer. "We tend to know when one of our TBMs is up for sale," says Daher Socata. "So we will offer the customer a free service, for example, and one of our service centres. This will make the asset more attractive to a buyer and keep the price higher."


The cost of an "average" 2007 model TBM 850, for example, has fallen from $2.4 million in the second quarter of 2009 to $2.1 million in the third quarter of 2010.
"In the business turboprop sector, prices have bottomed out and the sales inventory has remained steady throughout the year."
The bulk of activity over the past few months has been focused at the high end of the market. Barber says: "There is a huge difference in demand for top-end rather than bottom-end aircraft. An average 2008 Gulfstream G550, for example, priced at $39 million in the second quarter of 2009, was worth $43 million in the third quarter of 2010. A similarly aged Global XRS will have climbed in value from $39 million to $41 million during the same period," he says.
Barber sounds a note of caution. "While buyers are starting to return, most are looking for a bargain and will hold out for a purchase," he says. "Deals continue to fall through because of unnecessary haggling, sometimes over the most minor issues."
This view is echoed by Stone, who says: "The people who really needed to sell their aircraft have already done so. Many sellers are waiting for the market to pick up and won't sell at any price now. Every once in a while a forced sale or two will come along and this will reset aircraft values."

Long endurance redefined with two new high-altitude unmanned aircraft

"Long endurance redefined with two new high-altitude unmanned aircraft"

Within the next year, two similar designs made by rival manufacturers will attempt to break the record for long-endurance flight by a high-altitude piston-powered aircraft and help establish a new class of flying vehicles aiming to perform a job now reserved for satellites.

As far as unmanned aircraft systems have come in the past decade, the emerging race to satisfy the US military's demand for unblinking sensor and communications relay coverage over vast areas will push designs and technology for unmanned aircraft even further.

Leading the quest are two rival designs so advanced that they have been in development and consumed hundreds of millions of dollars in investment over nearly a decade to reach this point.

The immediate goal for the competing teams is to shatter that record held by the unmanned, gas-powered Boeing Condor and set in 1988 by circling over Moses Lake, Washington, at higher than 65,000ft (19,830m) for more than 59h.

By contrast, GO (pronounced "Geo") is designed to fly at least seven days, or nearly three times the endurance of the Condor standard.

The Phantom Eye demonstrator, smaller by 40% compared with the planned full-scale version, should fly 96h, or four days. At full scale, the Phantom Eye is designed to remain airborne for seven to 10 days.

In operations, such endurance could revolutionise the persistent surveillance mission. A system of two aircraft could establish a permanent orbit, with each aircraft alternating time on station in weekly cycles. From a vantage point above 65,000ft, the GO or Phantom Eye could stare up to 480km (260nm) in any direction. That is not a trivial distance in current operations. With a 965km coverage diameter, such aircraft see nearly the entirety of Afghanistan in a single 360ยบ sweep of its sensor aperture or antenna. In another example, if either aircraft was perched above London, the area of coverage would extend from the eastern shore of Ireland to the western border of southern Germany.

Other aircraft in the US military's repertoire - notably the manned Lockheed U-2 and unmanned Northrop Grumman RQ-4 - already provide such coverage but at only a fraction of the endurance.

To deliver the next leap in endurance at such altitudes, both AeroVironment and Boeing have decided to boldly switch from fossil fuels to hydrogen as the source of power for each aircraft's piston engine. In both cases, hydrogen is burned as a gas but is stored on board the aircraft as a liquid.

The long-term viability of the Phantom Eye and GO concept may heavily depend on whether the aircraft makes can prove that such fuel is a practical alternative to petroleum.

As a fuel source, hydrogen has much to offer. As the most abundant gas in the universe, there is no shortage of raw material. Hydrogen offers three times the energy density of petroleum-based fuel, with a corresponding improvement in aircraft endurance. Finally, hydrogen is a clean source of power, leaving water as the only by-product after being burned.

Despite these advantages, it is not difficult to grasp why Boeing has never in its storied history attempted to power an aircraft with hydrogen. When stored as a liquid, hydrogen requires special insulation, as its boiling point is -253e_SDgrC (-423e_SDgrF). Besides the cryogenic cooling requirements, long-term storage and transport is also a problem. The liquid form of hydrogen evaporates at a rate of roughly 1% a day even when properly cooled.

In addition to the fuel challenges, an aircraft that continuously operates for a week or more poses no small new burden on the US military's already strained system for processing, exploiting and disseminating intelligence data. On the other hand, military officials are rushing as many new airborne intelligence assets as possible into Afghanistan.

Indeed, the US military's support for GO and Phantom Eye is strong and growing. Launched as a joint concept technology demonstration by US Special Operations Command in fiscal year 2008, GO now has six agency sponsors, including the US Coast Guard. Phantom Eye has been funded primarily by Boeing and industrial partners, but has the Defense Advanced Research Projects Agency (DARPA) and NASA as supporters.

To fight insurgencies in Afghanistan and Iraq over the past decade, military officials have demanded ever-increasing levels of unbroken surveillance across large areas. The 10h endurance of the human-limited U-2 fleet would continue to be used, but more capability was needed. Even the 35h-endurance provided by Northrop's jet-powered Global Hawk is unable to supply the persistence demanded by operators.

In the last few years, the Department of Defense has launched several experiments in a seemingly desperate attempt to fulfil demands for a surveillance capability that never blinks, but is cheaper to operate and easier to adapt or upgrade than an orbital satellite.

The various experiments cover a wide range of potential technologies, to include hydrogen- and solar-powered aircraft, as well as fixed-wing and airship approaches. GO and Phantom Eye fall into the category of hydrogen-powered, fixed-wing aircraft. DARPA's Vulture programme seeks to invent a solar-powered aircraft with endurance not measured in hours, days or even months, but years.

AIRSHIP TECHNOLOGY

Airship technology has also benefited from a revival of interest. Lockheed Martin is developing a lighter-than-air airship called Isis (integrated sensor is structure), which could remain on station for months to sweep the air and the ground for targets across hundreds of kilometres.

Meanwhile, the army has awarded a Northrop/Hybrid Air Vehicles team a contract to develop and deploy within 18 months a hybrid airship called the long-endurance multi-intelligence vehicle (LEMV), a medium-altitude surveillance aircraft that could be adapted in the future for airlift roles.

Each concept is seeking to overcome a wide range of challenges - technological, logistical and operational - that have prevented their widespread use over a century of powered flight history.

Compared with the DoD's alternative experiments, the GO and Phantom Eye offer obvious attractions. If the fuel source issues can be worked out, the concept is a direct extension - albeit with a radical change in endurance - of operations now performed by the U-2 and RQ-4. Compared with airships and five-year-long sorties by Vulture aircraft, the objectives of Phantom Eye and GO appear almost conventional.

The concept also has its followers. In the United Arab Emirates, for example, aerial target maker Adcom Systems has unveiled the SmartEye unmanned aircraft system, which is advertised to be seeking endurance up to 135h, or more than five days. However, there is no record that SmartEye has yet flown, although the company claimed the aircraft would be ready for first flight months ago.

As the trailblazer in high-altitude, unmanned flight, Northrop also clearly recognises the market's interest in even longer-duration flight than that of Global Hawk.

Although there are no public plans to boost the endurance of the RQ-4, Northrop is pursuing other options to extend the aircraft's range.

DARPA awarded a $33 million contract to Northrop in early July to demonstrate aerial refuelling for the Global Hawk fleet. Under the KQ-X concept, a probe-equipped RQ-4 will demonstrate passing fuel in flight to another Global Hawk equipped with a drogue.

The planned demonstration involving both NASA-owned RQ-4 Block 0 aircraft is intended to show that a single Global Hawk can remain in flight and on station as long as the operator wants. The challenge will be proving that aerial refuelling is feasible at very high altitudes.

Northrop's KC-X strategy was unveiled in the months leading up to the first flight of the GO and Phantom Eye, which is perhaps no accident. Briefing reporters in June, Boeing PhantomWorks president Darryl Davis bluntly predicted that Phantom Eye "will be less expensive than Global Hawk", although he offered no specifics.

AeroVironment, meanwhile, has republished on its web site a 2007 academic paper from the Naval Postgraduate School arguing that GO would be 77.7% cheaper to operate over its lifetime than the RQ-4.

FUEL CONSUMPTION

The key difference in cost between the two aircraft is fuel consumption, according to the paper. GO would burn 455kg (1,000lb) on each mission, compared with about 6,800kg for the jet-powered Global Hawk. At the same time, the GO mission would extend over several days, whereas Global Hawk would land within 24h. Although liquid hydrogen is far more expensive to buy, the fact that GO would burn far less fuel would generate huge cost savings compared with Global Hawk, the paper says.

Asked to respond, Northrop's analysts noted several flaws in the three-year-old paper's arguments.

Most notably, fuel cost represents only 1% of the operating cost for Global Hawk, with the balance spent on required systems and manpower that also must be spent on GO.

In addition, as a demonstration aircraft, GO is not designed to meet airworthiness standards. If GO becomes a programme of record, Northrop says, military officials will require such an aircraft to prove it can reliably operate in the national airspace, which will dramatically raise the cost of development.

Global Hawk is classified by the USAF as a "global reach" aircraft, meaning it must be able to self-deploy to any location. For the Global Hawk, that designation requires a unique level of airworthiness testing not applied to other unmanned aircraft, such as the General Atomics MQ-1 and MQ-9 Reaper. Given the GO's promised capabilities, Northrop's analysis would expect such an aircraft to meet similar standards if the programme moves beyond a demonstration.

Tim Conver, AeroVironment chief executive, chairman and president, explained Global Observer's possible uses in a teleconference call with market analysts on 24 June.

"We envision that initial applications for Global Observer will address many of the communication relays, and intelligence surveillance, and reconnaissance needs of the current sponsors," Conver said. "Other applications are likely to follow."

It is possible that both GO and Phantom Eye could find small niches in the diverse market for special mission platforms. The army's special forces appears to be interested in GO especially as a communications relay aircraft, eliminating the need to rely on expensive commercial satellite networks to transfer sometimes sensitive information.

Meanwhile, Boeing has pitched Phantom Eye as part of its portfolio of options for detecting missile launches. In a May presentation, a Boeing official's slide on Phantom Eye was titled "persistent [intelligence, surveillance and reconnaissance] enables early intercept".

As it stands, GO is scheduled to complete development and be available for demonstration uses by air force special operations command next year. AeroVironment has received about $120 million to deliver three aircraft for the joint concept technology demonstration.

AeroVironment moved the first airframe to Edwards AFB, California in May to complete ground tests while the second aircraft is in final assembly.

Boeing's PhantomWorks division appears to be trailing the activity of its rival by a few months. The company staged a roll-out of the Phantom Eye demonstrator in July. Notices posted inside the factory during a June tour indicated that first flight was scheduled for the week of 20 January.

The rival manufacturers have adopted the same type of engine, but took slightly different approaches. AeroVironment developed and qualified its own engine. Boeing, meanwhile, adapted a 2.3L-engine from a small truck built by Ford.

In both cases, the hydrogen is stored as a liquid but burned as a gas. The gas is funnelled from the storage tank through a heat exchanger, where it converts into a gas. The fuel enters the engine at near room temperature, and drives two propellers generating 150hp (110kW) each. On the AeroVironment aircraft, the energy from two engines drives four propellers.

Boeing makes progress with unmanned programmes

"AUVSI: Boeing makes progress with unmanned programmes"


Boeing (booth 2600) is at the show celebrating the first anniversary of the creation of its dedicated unmanned division as it makes progress with a plethora of unmanned air vehicle programs.
Development work on the A160 Hummingbird (see cutaway drawing this issue, P16-17) continues apace, with the company confident that it can extend the helicopter's endurance beyond the 18h already demonstrated.
"We continue to work on refinements that we think will get it over 20h," says Boeing Military Aircraft director of unmanned airborne systems Vic Sweberg.
He says the loss of a US Army Aviation Applied Technology Directorate-owned Hummingbird late last month is "still under investigation. You learn from these things and move on."
He adds: "It was in flight and went into autorotation. There were no injuries or fire on the ground, but it was pretty much a complete loss."
Meanwhile, low-speed taxi tests of Boeing's Phantom Ray demonstrator have been carried out in St. Louis, and the aircraft is due to be transported to the Dryden Flight Research Center atop NASA's Boeing 747 Space Shuttle transporter aircraft for an expected first flight in December.
The Phantom Ray will be used to test technology that could be used to meet future US Air Force and US Navy requirements, known as MQ-X and Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS) respectively.
"We don't anticipate MQ-X in the near-term at all," says Sweberg. "UCLASS came up rather swiftly. We think that the Navy has identified a critical need, but they don't have a definitive set of requirements yet.
"We're pretty confident that Phantom Ray as it is today will not be what we offer lock stock and barrel for MQ-X and UCLASS," he adds.
Sweberg says the "current plan" for the first flight of the Phantom Eye high-altitude, long-endurance demonstrator is "early in the first-quarter 2011 timeframe."

Indian investment in MAV technology.


Defence Research and Development Organization (DRDO) has been entrusted with the Rs 100 crore Design and Development of Micro and Nano Air Vehicle Project to be deployed in countering terrorism and insurgency during low intensity conflicts, Dr Prahlada, Chief Controller (R&D) DRDO commenting today in Mangalore.
Speaking after inaugurating the three-day All India seminar on ‘Micro and Nano Air Vehicles,’ jointly organised by National Design and Research Forum (NDRF) and the Institute of Engineers (India), Dr Prahlada said as many as 30 institutions across the country, including colleges and universities were involved in the project.
Stating the DRDO was committed to supporting the Para Military Forces involved in maintaining internal security, Dr Prahlada said the Micro Air Vehichles (MAVs) would play a vital role during low intensity conflicts, surveillance, reconnaissance, fire, floods, earthquakes, gas leads, search and rescue, explosive detection and several other applications.
According to Prahlada, DRDO has the capability to build MAVs as small as 300 mm and weighing 300 gms. Efforts are on to bring it down to 100 mm to 200 mm and to less than 200 gms, he told reporters. “MAVs are small, almost bird-like. They are accurate and they cost very less,” Prahalada said, adding, “they can be manufactured in big numbers very, very cheap.”
Meanwhile, Former IISC Professor and founder of Drone Aerospace Systems Dr. Krishna Venkatesh has been invited to give a presentation on his findings on MAVs during the Knowledge Utsav, India’s largest R&D conference. The conference will witness the largest ever presentation of over 400 research papers across 44 disciplines and more than 100 inspiration talks.
The conference is organized by EDU.IN in association with Tumkur University and Jain Research Foundation (JGi). It will be held on August 28, 2010, Saturday at the Jain University, Global Campus, Kanakapura Taluk, Bangalore Rural.
Dr. Venkatesh is also one of the key members of the research paper review panel. Some of India’s leading Scientist and Researchers are part of this panel. Out of total 420 papers which will be presented at the Knowledge Utsav, the panel will be selecting around 250 research papers which will be published in some of the leading publications around the world.
