1.8 DESCENT
The DES page is used to monitor all Descent-related parameters.
1.8.1 Descent Target Speed
The FMS-commanded descent target speed will account for the arrival airport speed restriction, all descent
ing vertical speed-controlled vertical guidance also known as “Path

paths.
If the FMS detects the airplane current speed below a certain threshold, it commands the Auto-thrust system to
advance the throttle levers from the IDLE position.
The FMS determines and displays the deceleration point ahead when the airplane must slow down.
NOTE: During descent on a steep GPP path, the displayed deceleration point may not ensure the
required deceleration; the crew should monitor the airplane speed under these conditions.
