BASIC AUTOPILOT OPERATION
The following describes basic autopilot functionality. A more detailed description follows in Section 7.4.
-
Autopilot Engagement
— The autopilot may be engaged by pushing the
AP Key
on the AFCS Control Unit.
Annunciations regarding the engagement are indicated on the PFD.
-
Autopilot Engagement with Flight Director Off
— Upon engagement, the autopilot will be set to hold
the current attitude of the airplane, if the flight director was not previously on. In this case, ‘PIT’ and ‘ROL’
will be annunciated.
-
Autopilot Engagement with Flight Director On
— If the flight director is on, the autopilot will smoothly
pitch and roll the airplane to capture the FD command bars. The prior flight director modes remain unchanged.
-
Autopilot Disengagement
— The most common way to disconnect the autopilot is to press and release the
AP DISC
Button
, which is located on the control wheel. An autopilot disconnect tone will be heard and
annunciated on the PFD. Other ways to disconnect the autopilot include:
»
Pressing the
AP Key
on the PFD or MFD.
»
Pressing the
GA Button
(Non E-AFCS equipped aircraft only).
»
Operating the
MET Switch.
»
Pulling the autopilot circuit breaker.
In the event of unexpected autopilot behavior, pressing and holding the
AP DISC
Button
will disconnect the
autopilot and remove all power to the servos.
