To M.Mouse:
The flaps were retracted from F30 to F25 and the thrust levers were not selected to idle.
Could you kindly provide a source to back up your statement?
I agree, from a procedural point of view, that it would not be logical to retard the thrust levers to idle in this situation but with unresponsive engines and no thrust increase with the thrust levers fire-walled, would it not be a natural reflex to retard the thrust levers to idle in an attempt to try a last ditch effort to spool up the engines manually, an attempt to initiate a thrust increase from idle conditions?
(Somewhat like gunning your car engine when the engine stalls and you try to recover by letting go of the accelerator and pushing it back in, in an attempt to recover from a stalling engine.)
