Hugh Somerville, of British Airways, said he thought the report's figures on aircraft fuel efficiency were "a gross overestimate".
At subsonic speeds, the aircraft guzzles fuel.

But it is the concept aircraft's fuel efficiency that is really making aircraft manufacturers take note.
The German Aerospace Centre has tested this idea in an aircraft using a fuel cell to power two electric motors built into the hub of an aircraft nose wheel.

It is gaining from strong aircraft demand in Asia and the Middle East, plus the need among the commercial airliners to replace their aging aircraft to improve fuel effiency.
FORBES: Five Stocks To Be Thankful For Amid The Market Turmoil
For a man who was staring death in the face a few weeks ago, trapped in the twisted wreckage of a light aircraft with aviation fuel leaking all around him, Nigel Farage is on remarkably good form.
With the aircraft's fuel pump, navigation equipment and radio paralysed, the pilots glided the plane to a lower altitude and landed it on an airfield near the village of Izhma in the Komi region, about 1, 500 km (930 miles) from Moscow.
But the shift towards synthetic fuel has provoked criticism, because when such fuel is made from coal and then burned in an aircraft engine, more greenhouse gases are emitted overall than would be produced if the aircraft simply burned conventional fuel derived from oil.
Preussag hopes to use the addition of Thomson's aircraft to negotiate cheaper fuel, for instance.
Plane manufacturers are ramping up production amid robust demand for fuel efficient aircraft, particularly from emerging markets.
About half the airlines' expenses, such as fuel, aircraft and overseas maintenance, are in stable currencies such as the dollar.
ECONOMIST: Will Asia��s woes force a downturn in the aviation business?
An aircraft flying at a faster speed consumes more fuel per distance than the same aircraft flying at a slower speed.
FORBES: Is The Next Boom In Travel A Sonic Boom From Boeing?
The report said the rockets damaged a commercial aircraft and set a fuel depot on fire before the blaze was brought under control.
Boeing has continued to upgrade its 747 in response to the Airbus challenge and with a slight twist brought out its smaller 787 Dreamliner aircraft with an increased fuel-saving design.
Other Intelligent Energy world's firsts in recent years include the development of the world's first hydrogen fuel cell motorbike and supplying the fuel cell system to Boeing which powered the world's first manned fuel cell aircraft.
ENGADGET: UK's first fuel cell-powered black cab hits the streets of London
Boeing (nyse: BA - news - people ) has continued to upgrade its 747 in response to the Airbus challenge and with a slight twist brought out its smaller 787 Dreamliner aircraft with an increased fuel-saving design.
The researchers claim that it would use 25% less fuel than current aircraft do.
The second would involve providing American ships and aircraft with supplies, including fuel and oil from Japanese stocks.
Boeing says the aircraft is 20% more fuel-efficient than similar sized airliners, a selling point for airlines for whom fuel costs are their biggest operational expense.
However, in view of its present high price, rhenium (used in highly fuel-efficient aircraft engines) is now recovered from scrap bimetallic catalysts used in the oil refining industry.
FORBES: Recycling Scrap Rare Metals Vital to Future Technologies
The drop in value of local currencies against the dollar has caused immense difficulties for Asian carriers: dollars are the currency in which aircraft are traded and aviation fuel is priced.
In January, the company reported reported earnings for the fourth quarter of 2012 that were down 37.8% year-over-year, and attributed the slide in part to the higher cost of renting aircraft, landing fees and fuel.

FORBES: Award Winning Travel Organizations Share their Global Vision
The Air Force, until strong-armed by a few legislators, rightly did not want as big a plane as the KC-30 for the simple reason that it is far better to have a larger number of smaller, more fuel-efficient aircraft capable of operating from many airfields.
Boeing claims the 7E7 would cut fuel burn by 20 percent over current aircraft and save airlines 10 percent on overall operating costs, citing new, fuel-sipping engines and lightweight materials that will also cut maintenance costs.
The aircraft have more capacity and greater fuel efficiency than the 737s they will replace.
FORBES: Southwest Gives Fleet A Facelift, And Saves Some Dough Too
The report said that during the crash-landing "a significant amount of fuel leaked from the aircraft but there was no fire".
