The PNF MCDU should display the F-PLN page to allow the pilot to monitor time, speed and altitude
predictions. This page also displays matched or missed information for constraints.
CHECK vertical mode CLB if NAV is engaged.
CHECK vertical mode OP CLB if HDG/TRK is engaged.
MONITORING THE ND (ROSE NAV OR ARC)
Displays the lateral and vertical paths, in the current AP/FD active modes.

MONITORING THE AP/FD MODES AND FMA
If CLB mode is engaged, the flight mode annunciator (FMA) and the navigation display (ND) show
the tactical situation as follows :
CASE 1
The FCU altitude is set above the next altitude constraint
CASE 2
The FCU selected altitude is set at the next altitude constraint

The aircraft will automatically levels off at this altitude.
To resume the climb automatically when the waypoint AAA is reached, apply the following
procedure during the level off (Position 4) :
SELECT the FCU altitude to the next constraint (if any) or the cruise FL.
PUSH the FCU ALT selector knob to arm CLB mode.

RECOMMENDATION
To ensure that you will not miss the next constraint, it is recommended to select the FCU
altitude to the next constraint as described above.
MONITORING THE CONSTRAINTS
SPEED, ALTITUDE and TIME constraint can be checked using MCDUs. Each constraint is
preceded by a star that indicates if the constraint is matched (magenta star) or missed (amber
star).

ALTITUDE CONSTRAINT
If an altitude constraint is predicted as missed , use the following procedure :
SET the FCU ALT to the next ALT CSTR
CHECK the position of the level off symbol on the ND (blue arrow) with respect to the
waypoint with the constraint.
DECREASE the target speed until the constraint is met.
SPEED CONSTRAINT
CHECK the SPD CSTR predictions on the MCDU.
A magenta or amber star (*) indicates that the aircraft will match or miss the constraint.
If the aircraft is to miss the constraint by more than 10 kt, the MCDU scratchpad displays “SPD
ERROR AT WPT ---- ”.
“CHECK GW” MESSAGE.
Refer to PRO-SUP-22 "CHECK GW MESSAGE"
HDG/TRK MODE ENGAGEMENT
If HDG/TRK is engaged, the guidance does not consider any F-PLN constraint. Therefore if
the pilot disengages NAV, CLB mode reverts to OP CLB.
SPEED SELECTION
If a specific speed is required :
TURN and PULL the SPD selector knob. (This changes the target speed to blue on the PFD
speed scale).
Predictions on the F-PLN page assume that the speed remains selected until the next
SPD LIM or SPD CSTR, or the next phase, whichever comes first.

EXPEDITE CLIMB
Applicable to:
The flight may use the expedite mode temporarily to clear a specified altitude or to match a
constraint.
PRESS EXPED push button on the FCU.
The AP acquires and maintains Green Dot speed. There is no benefit to use expedite mode above
FL 250. The Mach corresponding to green dot is too low to maintain an increased vertical speed.
To revert to normal climb :
PUSH ALT selector knob CLB mode will engage.
Note: Pulling ALT or V/S or SPD/MACH knob also disengages EXPEDITE.
PRESSING EXPED push button never disengages the mode.
IMMEDIATE RETURN TO ORIGIN AIRPORT
Applicable to:
If the SEC F-PLN has been prepared for an immediate return to the airport of origin :
ACTIVATE the SEC F-PLN.
PERFORM a DIR TO the appropriate waypoint.
