I would like to be better at manual flying and probably don't do enough, but departing london TMA with it's many level offs, heading and frequency changes on raw data might be bad "threat error management"
Those of us who are bus drivers, are really just setting an attitude which the computer holds anyway.
If you look at the failures on a bus that would lead to loss of A/P and F/D and require raw data flying (eg dual SFCC) most would not leave you in normal law,
so maybe we need to practice direct law flying as well.
If I am ever (un)fortunate enough to fly with A340 chap who never uses automatics below 10,000 and never touches speedbrakes due to perfect descent planning, I will offer to turn a couple of flight control computers off for him as well and prepare to be amazed at his skills.
