To M.Mouse:
The flaps were reduced from F30 to F25. Approach idle would have been minimum idle speed had the thrust levers been closed, which they weren't anyway.
Even if the flaps had been reduced to less than F25 the idle speed would be irrelevant unless the thrust levers were closed, therefore, I fail to understand how the situation would have been aggravated.
There is no mention made about selecting F25 in any AAIB reports i have read sofar. If there was an anticipation to GA, flap selection would have been less than F25, at least to F20, taking the flaps out of the landing position which would mean (as explained earlier) engine EECs would be set for minimum idle. If the thrust levers were even momentarily moved to idle, to minimum idle they would have gone.
Same as for the flap scheduling, there is also no mention if the thrust levers had been retarded to idle, even if only for a short period. Thrust levers in idle, same as your claim flaps were selected to F25, are not mentioned in the AAIB reports but it it does not necessarily mean it did not occur.
