Being as inquisitive as I am I see where a line was added to the aircraft.cfg file to disconnect the AP when the Yoke is moved (as per the Changes menu)

I think CS forgot to add it to the B773 and B774 models??

AP_VS_maxcontrol=30
AP_FLCH_speed=2
AP_FLCH_window=16

[gpws]
max_warning_height=0.1

Maybe should be:-

AP_VS_maxcontrol=30
AP_FLCH_speed=2
AP_FLCH_window=16
AP_joystick_disc=25000

[gpws]
max_warning_height=0.1

And I haven't flown it yet!!  :)
