....the engine EECs would have automatically reverted from approach idle to minimum idle, aggravating the situation in this particular case.
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.
