pseudo waypoint with NAV mode engaged (or LOC*, LOC).
EXPEDITE DESCENT (IF INSTALLED)
Applicable to: ALL
�� When ATC requires a rapid descent :
DEPRESS THE EXPED pushbutton
Flight guidance (FG) pitches the aircraft to acquire and maintain 0.80/340. FG orders a pitch
rate that produces no more than 0.15 g. The pilot can use this mode to initiate an emergency
descent. To resume normal descent, PUSH the ALT selection knob or engage any other vertical
mode.

MONITORING THE NAVIGATION IN THE TERMINAL CONTROL AREA
Applicable to:
If the MCDU “SYSTEM RNP IS XX.X” message is displayed, the pilot will verify the manually-entered
RNP value in the REQUIRED field of the PROG page and clear or modify it, if it is not in accordance
with the RNP value specified in the area (NAV or approach chart).

If the MCDU “AREA RNP IS XX.X” message or “PROCEDURE RNP IS XX.X” message is displayed,
the pilot the manually-entered RNP value in the REQUIRED field of the PROG page and clear or
modify it, if it is not in accordance with the RNP value specified in the area (NAV or approach chart).
TOO STEEP PATH
Applicable to:
“TOO STEEP PATH AHEAD” appears on the MCDU scratchpad, when the system predicts this
situation, and TOO STEEP PATH is displayed on the F-PLN page.
When the aircraft is crossing the first waypoint of a TOO STEEP PATH, the system computes a
flyable descent profile (with an idle segment). The VDEV makes a jump because it is related to a new
profile.

PROCEDURE
�� When passing the first waypoint of the TOO STEEP PATH :
MONITOR VDEV and predictions at the next CSTR waypoint.
If required, EXTEND the speedbrakes before seeing the “MORE DRAG” (or “AIRBRAKES”)
message.
CONSIDER using a holding pattern, if necessary.

HOLDING PATTERN
Applicable to: ALL
A hold may be required during the descent, and may be manually inserted.
PROCEDURE
PRESS the F-PLN key.
SELECT the lateral revision page.
SELECT the HOLD prompt.
CHECK the HOLDING data, and MODIFY it if necessary.
CHECK the temporary flight plan and INSERT the holding pattern in it.
Note: If the holding fix is close to the DECEL pseudo waypoint and the speed is managed,
manually activate the approach phase to change the managed target speed to approach
speed (VAPP). This will avoid having an increase of speed not appropriate.
