Recent posts, HPSOV L, Vessbot, Judd, #77-79, consider the same problem from different aspects - situation awareness.
Perception, change, understanding, time, are critical components of awareness - how we make sense of things.
Reluctance to 'click click', 'my plane'; the difficulty is in identifying the need to act, that some situations require a change of action.
Pilots must consider the 'AP's perception', requires working knowledge, limitations, awareness.
Viewing accidents from human viewpoint usually concludes human error - more training. Alternatively, considering a joint human - automation system, what might be concluded as a perfectly serviceable aircraft, becomes an inadequate combination of man and machine in a particular situation (Man Machine Situation).
Not more training, but improved system alerting that auto-thrust is not available in some circumstances, that attempting to engage AP outside limits gives a 'uh uh' alert, cueing a change in awareness, an awareness which is assumed by others to include every circumstance, but circumstances are rarely as assumed.
First check assumptions, reconsider circumstances - avoid.
Improve the machine to aid the pilot - joint system.
Last, reluctantly consider the very difficult task of changing human behaviour which can never be assured or as assumed - not all situations are foreseeable.
Slowly deteriorating situations are difficult to identify, cf 'Boiling Frog'. There is a natural reluctance to act because action is already in hand, except that as situations change so must actions, which requires understanding, awareness, mental skills - which degrade faster than manual skills.
The industry requires a combination of improvements for man and machine, but the myth that human aspects are more effective come from management thinking. The issue is not about manual flight, its knowing when to fly manually, and adapting normal skills for abnormal situations.
