Descent Page Preflight #
Descent Page Preflight – Description #
ACTIVE MODE – Indicates the active mode speed target in green (managed or selected). Cannot be modified through this field.
TIME, UTC and DEST EFOB – Before takeoff, displays the flight time (time) to destination and the predicted landing fuel. After takeoff, it displays the predicted arrival time at destination (UTC) and the predicted landing fuel. If the pilots enter an estimated takeoff time, the predicted arrival time (UTC) at destination displays automatically.
MANAGED – Indicates the speed/mach around which the FMGC-computed descent profile is built. The default values are based on cost index. If modified, the value will display in large font.
PREV PHASE – Provides access to Cruise page – LS 6L.
NEXT PHASE – Provides access to Approach Page page – LS 6R.

Description #
ACTIVE MODE – Indicates the active mode speed target in green (managed or selected). Cannot be modified through this field.
TIME, UTC and DEST EFOB – Before takeoff, displays the flight time (time) to destination and the predicted landing fuel. After takeoff, it displays the predicted arrival time at destination (UTC) and the predicted landing fuel. If the pilots enter an estimated takeoff time, the predicted arrival time (UTC) at destination displays automatically.
SPEED TARGETS – Current speed targets for both MANAGED and SELECTED speed. The active mode is in large font.
ACTIVATE APPR PHASE – Appears when displayed page is active. First push causes CONFIRM APPR PHASE prompt to appear; second push activates the APPR PHASE.
NEXT PHASE – Provides access to Approach Page page – LS 6R.
Activate Appr Phase #
Appears when displayed page is active. First push causes CONFIRM APPR PHASE prompt to appear; second push activates the APPR PHASE.
If the approach phase is not confirmed, the CONFIRM APPR PHASE prompt reverts to the ACTIVATE APPR PHASE prompt when a mode key or line select key other than 6L is pushed, or if a flight phase transition occurs.
If the approach phase is activated inadvertently, reentering the CRZ FL into the PROG page restores the climb phase.
Click on LS 6L to confirm approach phase.
Confirm Approach Phase #
After CONFIRM APPR PHASE prompt appears; second push activates the APPR PHASE.
If the approach phase is not confirmed, the CONFIRM APPR PHASE prompt reverts to the ACTIVATE APPR PHASE prompt when a mode key or line select key other than 6L is pushed, or if a flight phase transition occurs.
If the approach phase is activated inadvertently, reentering the CRZ FL into the PROG page restores the climb phase.
Click on LS 6L to activate approach phase.
Target Altitude #
Displays the altitude to which the predictions in lines 3R, 4R, or 5R are referenced.
Performance Predictions #
Displays the predicted ETA and the distance required to reach the altitude shown on line 2R. The predictions are paired to the lines on the left side of the screen.
Line 3R displays predicted descent performance for speed.
Line 4R displays predicted descent performance for selected speed/Mach.
Line 5R displays predicted descent performance for EXP DES.
The line corresponding to the active mode displays in large font.
