The whole point of being a trainer is to make the operations safer.
3-man LH defies that purpose. Time to make a stand!
Oh, and 8 hard landings last month. Maybe it's time they use the FDAP properly and check if it isn't a new trend because of 250h pilots landing a (330T) jet for the first time? Maybe the data won't support it.
But FDAP's initial purpose was just that: identifying worrying trends so training, SOPs and maybe recruitment can be amended. Not used to single out the odd mistake that wasn't ASRed.
