Starting/Stopping Auto Descent
Altitude Assist features require the system to include an altitude input
device. The following procedure is used to start or stop Auto Descent.
Auto Descent calculates the distance remaining in your Active flight
plan, and based on the glide path angle, the altitude you are descending
to, and your present altitude, alerts you with a message when you
should begin and end your descent. For a complete discussion on Auto
Descent, refer to Setting/Editing Auto Descent Values.
