If the disconnect is accompanied by an amber AP with a red X, the autopilot will not be available 
however the flight director will still be functional. 

In the event of a GMC failure, pressing the G5 knob will acknowledge the disconnect tone.

NOTE 

If  ESP  is  active  for  approximately  10  seconds,  the  autopilot  will  automatically  engage  in  LVL 
mode,  an  aural  ‘ENGAGING  AUTOPILOT’  will  be  played,  (or  a  Sonalert  tone  will  sound  for 
installations without a supported audio panel) and the autopilot will roll the wings level and fly at 
zero-vertical speed.    Refer to Section 7, System Description for further information. 

ESP will be disabled by pressing and holding the AP DISC / TRIM INT button.    Releasing the
