MANAGED.
The pilot cannot modify it from 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 This field displays the FMGS computed ECON speed/Mach (Refer to
STLO-22_20_R-40-10 OPTIMUM TARGET SPEED FOR CLIMB, CRUISE,
AND DESCENT (ECON SPD/MACH)).
Before CLIMB phase is active, if the preselected speed mode is
SELECTED, a star is displayed next to the MANAGED speed. Pressing
the 3L key in this case preselects MANAGED speed, and 4L reverts to
brackets.
[ 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 enter a preselected speed only.
�� 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 modify it directly in 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.

EXPEDITE
This field is blank as long as the aircraft is in preflight.
This field displays this legend when the takeoff or climb phase is active.
It indicates the time and distance required to reach the altitude displayed in
the 2R field, in case of climb at green dot.
[ 6L ] PREV PHASE This field displays this legend if 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 The system displays the EO CLR prompt in case of engine out in climb.
[ 2R ] PRED TO... This field displays the target altitude for the predictions shown in 3R, 4R,
or 5R. It defaults to FCU altitude, but the pilot can modify it to any altitude
below CRZ FL.
[ 3R ]
[ 4R ]
[ 5R ]
These fields show time and distance predictions for the target altitude
selected in [ 2R ], computed for the current vertical mode and speed mode
(MANAGED, SELECTED, or EXPEDITE).
These fields are displayed only while the takeoff, or climb phase is active.
[ 6R ] NEXT PHASE The pilot presses this key to call up the PERF CRZ page.
