The time is only computed in cruise phase.
[ 5L ] The crew may enter a fifth airport in this field, using the 4–letter
ICAO code. The field may be modified at any time, even when “LIST
FROZEN” is displayed.
If the crew enters an airport that is not in the database, a “NOT IN DATABASE” message appears
in the scratchpad.

[6L] FREEZE/UNFREEZE
(cyan)
This prompt enables the pilot to freeze and unfreeze the list of four
airports.
The list is automatically frozen when accessing page 2. It will remain
frozen until returning to page 1.
The “LIST FROZEN” message is always displayed on page 2.
[6R] EFOB/WIND Gives access to page 2.
Pressing this prompt automatically freezes the list of the four closest
airports.
CLOSEST AIRPORTS 2 PAGE
[ 1L ] - [ 1R ] EFOB (green)
to [5L] - [5R] EFF WIND
(cyan)
Displays the EFOB at each airport. The EFOB is only computed in
cruise phase.
Used to enter an estimated effective wind (headwind or tailwind)
along the route to the airport. If the entry is preceded by “+”, “T”, or
“TL”, a tailwind is assumed.
If the entry is preceded by “–”, “H”, or “HD”, a headwind is assumed.
This field displays in small font a default value, based on the current
wind experienced by the aircraft. The crew can modify this value, it is
then displayed in large font.
The effective wind is used to compute the EFOB and time to reach
the airport.
[ 5L ] The crew may enter a fifth airport in this field, using the 4–letter
ICAO code. The field may be modified at any time, even when “LIST
FROZEN” is displayed.
If the crew enters an airport that is not in the database, a “NOT IN DATABASE” message appears
in the scratchpad.

Note: If the aircraft position becomes invalid, all BRG, ‐ DIST, UTC fields are dashed. The
CLOSEST AIRPORTS page still displays the last available list of 4 closest airports and
the last crew-defined airport (if any). FREEZE/UNFREEZE and EFOB/WIND prompts
are removed, LIST FROZEN is displayed, and the A/C POSITION INVALID message
is displayed in the scratchpad. Page 2 cannot be accessed.
‐ Predictions (EFOB, TIME) displayed on the CLOSEST AIRPORTS page assume :
• ECON CRZ speed (managed) or current selected speed (selected) is kept ;
• CI (for managed speed only) and CRZ FL from the active F-PLN are kept
• A constant wind value ;
• In case of engine out, the aircraft altitude is the minimum of (CRZ FL, EO MAX
ALT) ;
• Downpath steps are not considered ;
• Descent fuel burn is a conservative value which only depends on the difference
between current CRZ ALT and the destination airport altitude.
EQUI-TIME POINT PAGE

The flight crew uses this page to request an equi-time point computation between two different
points (airport, navaid, runway, NDB or waypoint). This pseudo-waypoint (ETP) is displayed on the
navigation display along the F-PLN. The EQUI-TIME POINT page is accessed by pressing the 6L
key on the DATA INDEX 1 page :
