What is also disturbing (or the FDR is not telling the truth due to some underlying problem in the TLAs?) to see is that in their 2nd previous landing they only set the TL2 to IDLE (while reversing TL1 as should). But in the previous landing (ie just before the accident) they reversed both TLs as one would with both TRs operating?
I have often flown with 1 TR U/S. Under the previous MEL, where it was advised not to select Idle Rev on the Inop Rev, I reckon I only remembered 50% of the time
If you find that disturbing, you must be perfect
I think you will find most A320 series pilots forgot this quite a lot of the time...
As to why they did it 3 different 3 ways in 3 different landings, I could make a set of guesses. However, lets leave that to the pros, and the trick cyclists they may bring in to analyse human behaviour... which I still contend is the likely basis of this accident.
