Automation
I personally feel that a lot of sensible things have been said on this thread. All accidents are being blamed on automation and lack of flying skills when the actual reasons for the accidents have been failures that went unnoticed.
Incase of the Turkish Airlines, the malfuntion in the Radio Altimeter led to the Auto throttle failure which should have been monitored especially when there was a training Captain on board.It was a failure to monitor the Flight Mode Annunciators.Also probably lack of knowledge. The event lasted a long time with the speed decaying.
The stall recovery procedures, wind shear escape manouvres, EGPWS Warning ,TCAS manouvres and upsets should be mandatory procedures and included in Simulator checks. The simulator time needs to be increased and taken more seriously. I have observed that a lot of times the crews reduce their 4 hour slots to practically 03 effective hours especially during graveyard shifts in order to get back to catch up on sleep or make it the nearest bar for Happy hours!These 4 hours were good enough in the old times when all the above manouvres were not included. Also hand flying approaches during line checks and inflight monitoring by Instructors and Examiners is not a bad idea ...although an unpalatable one for a lot of us.
