POM DESCRIPTION
Approach
The approach mode is armed using the APR button. When capture
criteria is met, the mode will activate and track the active navigation
source.
Takeoff and Go-around
The Takeoff or Go-around modes are activated by pushing either TO/GA
switch. Pressing it also disengages the autopilot and sequences the FMS
to the missed approach.
If on the ground, the takeoff mode is activated and in flight, the go-
around mode is activated. The takeoff and go-around modes command
wings level and a fixed pitch attitude based on the number of operating
engines and flap setting.
Autopilot
The autopilot system follows attitude command inputs from the flight
director. The autopilot system controls the pitch servo, which moves the
elevator and the roll servo which moves both ailerons. The autopilot also
controls the pitch trim tabs (pitch auto-trim) when it is engaged. A green
AP is displayed on the FMA when engaged.
When disconnected, the AP symbol flashes in amber or red color based
on whether disconnect was commanded or not. The amber normal
disengagement indication will self-acknowledge in 5 seconds, but the red
abnormal disconnect annunciation requires the yoke mounted AP
ACK/DISC or the AFCS/TRIM MASTER button to be pushed to clear
the red indication and silence the aural alert. This AP ACK/DISC button
can also be used to disengage the autopilot in addition to the AP
engage/disengage button on the AFCS Mode Control panel.
