Line 1 In this field, the flight crew can either enter a geographic step, or an altitude
for an optimal step.
Line 2 to line 4 STEP AT (large blue font).
The flight crew can only enter geographic steps in these fields.
Displays the point at which the active step begins. It may be either an active
(or secondary) flight plan waypoint, or an inserted optimal point (OPT).
DIST / TIME (UTC)
(green small font)
Displays the distance to go and time from the present aircraft position along
the flight plan to the step point.
ALT Displays the altitude to step to, and allows entry of the optimal step format :
FL or ALT.
Note: The following messages may be displayed in the DIST / TIME
field :
ABOVE MAX, if the step altitude exceeds the Max altitude‐
computed by the FMS (Refer to STLO-22_20_R-40-30-A
OTHER COMPUTATIONS - Recommended maximum altitude
(REC MAX)).
IGNORED, if the step end point is less than 50 nm from the top‐
of descent.
STEP ‐NOW, if the aircraft is within 20 nm from the step point.
NO OPTIMAL, if an inserted optimal step falls in a discontinuity‐
due to a flight plan change, or if a time constraint exists in the
flight plan.
[ 5L ] TO OPT PT
(green small font)
This field displays the distance and time to a non inserted optimal step point
if one exists.
[ 6L ] RETURN The flight crew presses this key to return the display to the previous page.
Note: On any flight plan change, an inserted optimal step remains in the
flight plan at a fixed distance to destination.

[ 5R ] SAVINGS This field displays the fuel and time savings before insertion of the optimal
step point.
Fuel savings are displayed in thousand of kilograms (or pounds) (maxi 99.9).
The value is preceded by :
“–” in case of fuel saving,
“+” in case of additional fuel cost.
Time savings are displayed in hours and minutes.
The value is preceded by
“–” in case of time saving,
“+” in case of additional time cost.
Note: If no optimal step point exists for the altitude displayed in [ 1R ],
the “NO OPTIMAL” message is displayed in the FUEL / TIME
field. This message is also displayed if the optimal step falls into a
discontinuity.
[ 6R ] INSERT (amber) This field displays INSERT when an optimal step point exists but is not yet
inserted. When INSERT is selected :
the optimal step point i‐s inserted into the flight plan.
OPT is displayed in line 1L.‐
optimal step distance and time are deleted in line 5L.‐
the * UPDATE blue prompt replaces the INSERT prompt.‐
UPDATE This prompt allows to compute another optimal step point.
The UPDATE prompt is then replaced by the *INSERT prompt.
DATA INDEX PAGES
Applicable to:
GENERAL
There are two INDEX pages :
The DATA INDEX 1/2 page gives access to various pages devoted to navigation.
The DATA INDEX 2/2 page lists the navigation data entered in the FMGS.
The pilot enters those items labeled “stored” and can modify them. The pilot can call up the others,
but cannot modify them.
The pilot calls up these pages by pressing the DATA key on the MCDU console :
