altitude)
This is the altitude at which the climb phase is triggered.
The target speed jumps to the initial climb speed.‐
The default value is 1 500 ft above runway elevation.‐
The flight crew can modify the value. The minimum value is 400 ft above‐
runway elevation. However, it is always higher than, or equal to, thrust
reduction altitude.
Note: A clearing action reverts both values to the defaulted ones.‐
When the flight crew selects an altitude on the FCU that is :‐
Below ACC, it brings the ACC down to this altitude.‐
Below THR RED, it brings THR RED and ACC down t‐o this
altitude. (The 400 ft minimum still applies).
[ 6L ] UPLINK TO DATA
This key calls up the UPLINK TO DATA REQ page. It is only displayed in the
PREFLIGHT and DONE phases, when ACARS is installed.
[ 1R ] RWY This field shows the takeoff runway selected on the active flight plan. The
flight crew cannot make an entry from this field. The field shows dashes, if
no runway has been inserted in the flight plan.
[ 2R ] TO SHIFT The takeoff shift is the distance in meters or feet between the beginning
of the runway and the aircraft’s takeoff position. When taking off from an
intersection, the flight crew should insert this value to ensure a correct
update of the FM position. The takeoff shift value must be positive, and
cannot be greater than the available takeoff run.
[ 3R ] FLAPS/THS This is an optional flight crew entry for the positions of the flaps and the
trimmable horizontal stabilizer (THS) at takeoff. The FLAP setting is used by
the FWC to trigger the “FLAP/MCDU DISAGREE” ECAM caution. The flight
crew can modify it until takeoff, by entering “UP X.X” or “X.X UP”, or “DN
X.X” or “X.X DN” for the THS.
[ 4R ] FLX TO TEMP The flight crew inserts the FLX TO temperature for FLX takeoff setting
purposes. It can only be entered during preflight. The system sends it to
the FADEC, and displays it on the upper ECAM display. The TEMP value is
always entered in degrees Celsius.
[ 5R ] ENG OUT ACC This field displays the engine-out ACC altitude, as defined in the database,
or as manually entered by the flight crew. This is for display only, as a
reminder. It cannot be cleared.
The above ACC altitude rules of [ 5L ], apply to this field.
[ 6R ] NEXT PAGE This key calls up the climb performance page.

The boxes are amber, as long as the flight crew does not make entries in
them.
The flight crew can modify any entry, as long as the takeoff phase is not
active.
Note: • If the flight crew does not enter V2, the SRS mode will not be
available at takeoff.
• If the flight crew has entered V1, V2 or VR and the takeoff
runway is changed, the MCDU scratchpad displays CHECK
TAKEOFF DATA, and V1, V2 and VR fields revert to amber
boxes.
[ 4L ] TRANS ALT
(Transion Altitude)
The flight crew can call this up from the database after the origin airport is
defined. The flight crew can modify it.

[ 5L ] THR RED (Thrust
Reduction altitude)
This is the altitude at which the flight crew should reduce the thrust from
TOGA/FLX to MAX CLIMB (CL detent) with all engines operative.
The default thrust reduction is 1 500 ft above the runway elevation.‐
The flight crew can modify this altitude : The minimum is 400 ft above the‐
runway elevation.
ACC (Acceleration
altitude)
This is the altitude at which the climb phase is triggered.
‐The target speed jumps to the initial climb speed.

The flight crew can modify the value. The minimum value is 400 ft above‐
