CLOSEST AIRPORTS
Applicable to:
The CLOSEST AIRPORTS page displays the four closest airports, from the position of the aircraft,
found in the navigation database (Refer to DSC-22_20-50-10-25 CLOSEST AIRPORTS PAGES),
and the 5th fifth airport, as selected by the crew.
For each airport, the FM computes :
The BRG/DIST/ESTIMATED UTC from the position of the aircraft to ‐ the corresponding airport.
‐ The EFOB at the airport, assuming an EFFECTIVE WIND (defaulted or entered by the pilot).

Note: When the CLOSEST AIRPORTS page 2 is selected, the list of airports is automatically
frozen, as indicated on the page.
The FUEL/TIME predictions to the closest airports use simplified assumptions :
‐ Managed speed profile in cruise, with the effective wind from the CLOSEST AIRPORTS page 2. In
case of EO, Engine Out condition is considered.
‐ Continuous descent from CRZ FL down to the airport elevation.
Note: In case SELECTED SPD is used, the CLOSEST AIRPORTS page still provides good use
to choose the applicable closest airport for diversion purposes. However, when SELECTED
SPD is significantly different from MANAGED SPD, the predictions in terms of time and fuel
must be disregarded since they are misleading.
The predictions may then be checked on the SEC F-PLN.

The crew can enter a time marker in the F-PLN A or B page. Once entered, the FMGS displays a
pseudo waypoint along the flight plan on the MCDU and on the Navigation Display. This pseudo
waypoint shows the predicted location of the aircraft at the entered time.
HOW TO INSERT A TIME MARKER
Applicable to:
WRITE the time marker in the scratchpad. The entry format is HHMM.
SELECT any left key of the F-PLN A or B page, to insert the time marker in the active flight plan.
The time marker is inserted in the flight plan according to time criteria, irrespective of the key
choosen for entry.
Up to four time markers may exist at a time. An attempt to enter a fifth time marker will cause the
“TIME MARKER LIST FULL” message to appear on the scratchpad.
The FMGS updates the time marker position with the predictions.
When the current clock time equals or exceeds the time marker entry, the FMGS sequences the time
marker (even in preflight).
