Would you listen to some of you? No wonder there's never going to be a pilot only forum on here. I would hazard a guess that less than 0.1% of all airline pilots have EVER performed high power ground run tests of engines. It's an an engineering function not a pilot function.
So, here we have some of the so called 'expert pilots' giving us the benefit of their engine ground run experience which amounts to about the same as a gnats fart!
The next thing is we have them telling us about how to chock the a/c. Thanks to an engineer who took the time to take the relevant bit out of Boeing's engineering manual.
Whilst this incident is sad for the injuries and the loss of an airframe, it has NOTHING to do with pilots or piloting. Yet, here we have a huge thread full of inane drivel and highly speculative pomposity about how it should have been done from the mouths of sad people who are either pilots with absolutely no experience of conducting high power, static, engine ground runs or else just anoraks who think they know everything because they have completed half their spotters handbook of registrations!
What we have here is some engineers and technicians messing up big time. That's it. End of story. But nooo... the anoraks have to start telling the rest of us how they would have conducted it and what they did wrong in Tolouse when in fact, the sum total of their experience in these things is ZERO.
