Standardised training syllabus is a nice aspiration but could easily lead to "flying by committee"
I will take my chances with self motivated, individual, professional diversity anyday.
I can just imagine the committee debating "when to put carb heat on" this would most likely be an annual event with no clear outcome, oh and the committee would need to stay in nice hotels in scenic holiday spots.
Cynical I know but in the real world natural selection leads to the adoption of sensible practices (well most of the time). If you try to get rid of human individuality, uniqueness and opinion (where discretion is valid) then we will all fly like clones with no enthusiasm or self expression and the world of aviation would be very dull indeed.
