speed degradation, even problems of rudder use during LPC/OPC EFATO drills
I don't want to burst to your bubble PP, but this sort of argument will not wash with those concerned. They only have to review LPC/OPC forms from all companies to realise these are errors made by all experience levels.
For what it is worth this issue should be broached by Balpa head office/NEC, on a similar vein to their European FTL campaign.
