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.

Applicable to:
TITLE CLB is in large white font when the climb phase is not active, and in large
green font if it is active.
[ 1L ] ACT MODE This field displays the active speed mode : SELECTED or MANAGED
(ECON). The pilot cannot modify it via this field.
[ 2L ] CI (Cost Index) This field displays the cost index, as initialized on the INIT A, or defaulted
from the database, or inserted in this field by the pilot. EO LRC automatically
replaces the cost index value in case of engine-out.
[ 3L ] MANAGED When the speed target is managed, the FMGS computes the ECON speed.
This field displays the ECON speed/Mach :
ECON is the optimum speed, considering the time and fuel cost ratio for the
active flight plan, weather data, cruise flight level, and aircraft gross weight.
Speed limits and speed constraints, if any, may prevent the aircraft from
flying at the ECON speed.
[ 4L ] PRESEL or
SELECTED
If the climb phase is not active :
This field displays PRESEL, as long as the climb phase is not active.
The pilot can only enter a preselected speed.
If the climb phase is active :
The title of this field becomes SELECTED.
This field displays the selected (or preselected) SPD or MACH target.
The pilot cannot directly modify it this field, but can adjust it with the
SPD/MACH selection knob on the FCU.
If the pilot pushes in the FCU SPD/MACH selection knob to revert to
managed speed, the system selects (or reselects) ECON SPD/MACH, and
[ 4L ] is blank.

[ 5L ] Blank or
EXPEDITE
This field is blank, as long as the climb phase is not active.
This field displays this legend when the climb phase is active.
It indicates the time and distance required to reach the altitude displayed in
the 2R field, in case of a climb at green dot.
[ 6L ] PREV PHASE This field displays this legend, if the climb phase is not active. The pilot
presses this key to call up the takeoff page.
[ 6L ] ACTIVATE APPR
PHASE
The field displays this legend, if the climb phase is active.
Pressing this key once displays “CONFIRM APPR PHASE*”.
Pressing it again activates the approach phase.
[ 1R ] EO CLR orDRT
CLB
The system displays the EO CLR prompt, in case of an engine-out in climb,
or DRT CLB when the crew selected a derated climb .
[ 2R ] PRED TO... This field displays the target altitude for the predictions shown in 3R, 4R, or
5R. It defaults to the FCU altitude, but the pilot can modify it to any altitude
below CRZ FL.
[ 3R ] or [ 4R ] or [ 5R ] These fields show target altitude predictions selected in the [ 2R ] field for
the current vertical mode and target speed.
[ 3R ] field : Predictions for ECON speed (managed)
[ 4R ] field : Predictions for SPD manually selected
[ 5R ] field : Predictions for climb at green dot (EXPEDITE speed).
These fields are only displayed while the takeoff, or climb phase is active.
[ 6R ] NEXT PHASE The pilot presses this key to call up the PERF CRZ page.
