Its not the work of the devil.
Its a tool which can be deployed to great advantage by an instructor.
Its more the self teaching then renforcement of bad practises which is the issue.
I completely agree with BPF and YW even when flying IFR in class A with the horizon visable my heads out the window. Its alot easier to maintain S&L using the real one than the AH. And once trimmed the aircraft does the flying so as long as you don't annoy her she will stay straight and level.
Record is 15mins and the length of Wales with no control inputs. Very stable day and no directs. Its quite a good training game to play with the FO's if you bitched at them for being out of trim they would just get bored with the nagging. Doing a rubbish 30 seconds hurts thier pride and is far greater motivation to trim it properly than nagging. After they can do it they trim it subconsiously.
