When I learnt to fly, AIRMANSHIP was something that was stressed, taught and encouraged. Sadly, we hardly ever hear that word today! There are times when good airmanship dictates that the AP should be used. However, if a pilot does not maintain a good level of competence in hand flying skills then he is displaying poor airmanship. Therefore, if it is prudent and safe to hand fly a departure or arrival then it should be hand flown in order to maintain these skills.
I had one trip in a "Classic" Boeing where, in accordance with the MEL, we dispatched with the 'Alt Sel' autopilot function inoperative but with the 'Alt Hold' function working. This meant that there was a high probability of an altitude bust with the AP engaged if the normal habit pattern and swith selections were followed. Therefore, it was much safer to hand fly the aircraft and scan the altimeter when levelling off. Oh, and that was into and then out of ORD!
Traditional stick and rudder skills are dying in both commercial and military aircraft due to the advent of electronic flight control systems with envelope protection. Soon, these skills will only reside in sport aviation. Let us practise and preserve these skills as much as we can - one day your life may depend on them.
