With Saj Ahmad's track record of getting his facts wrong, it's not surprising that he does so consistently over the Pratt & Whitney GTF engine.
Ahmad persistently writes: PW won't say definitively what the fuel and maintenance savings are for the engine. He constantly claims PW only promotes "double digit" savings. Fact: P&W CEO David Hess said in an interview with Bloomberg News that the engine saves 16% on fuel and 20% on maintenance costs. How much more definitive can you get than that?
Ahmad constantly writes that Boeing isn't interested in the GTF engine. Fact: Aircraft Technology magazine got a very different story from Mike Bair, head of the 737 future programme. Boeing likes the engine, has no concerns about its reliability and Bair says he's "glad Pratt is back in the game."Ahmad also ignores statements by Airbus' John Leahy that Airbus has no concerns about the GTF.
Ahmad writes that airlines are highly skeptical of the GTF. Fact: Airlines are very interested in the GTF. They have questions, certainly--but the same is true about LEAP-X. Flight Global has an extensive story about the considerations of both engines.
Ahmad writes that Bombardier's CSeries, which uses the GTF, was launched in 2006 (despite the fact that Bombardier itself says 2008). Fact: Flight Global has it right in a long article about the challenges to Airbus and Boeing.
