Think a bit...
What could be the reason of those 55% compliance rate?
I have raised a point of flying, fatigue, It happened I just forgot to shut down one engine for taxi after a long duty.... And so what? is this unprofessionalism?
So, before trying to shot me, try not to act as one of our company manager, and try to understand WHY the trend went that low.
Shall I shut down an engine for taxi if I feel it is not the right moment, time to do it?
And don't tell me I could explain them, there is nothing like explaining them.
Especially after their legal 23h FDP turns...
