as little as possible as:
a) I have alas only 2 hands and one is used to hold the regenerator (a.k.a known as coffee)
b) usually I need both hands to hold the newspaper anyway
c) hand flying annoys the F/O who the has to turn or push knobs and thumbwheels, pushbuttons and switches, thus preventing him of taking care of the nearest and cutest flight chick
d) most passenger quickly resort to the infamous bag as I have yet to see a pilot act on the controls as smoothly precisely as the A/P
e) I leave the hand flying for my off time SEP flying
f) my company prescribes: switch A/P to on when climb attitude has been established
g) the modest salarium attributed by my employer prevents me from working
Thanks to "George", faithful companion
