[6R] EFOB/WIND Gives access to page 2.
Pressing this prompt automatically freezes the list of the four closest airports.
Note: If the aircraft position becomes invalid, all fields are ‐ dashed, 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 page assume :
• ECON CRZ speed (managed) or current selected speed (selected) ;
• CI (for managed speed only) and CRZ FL from primary F-PLN are kept
• 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 destination altitude.

EQUI-TIME POINT PAGE
Applicable to:
The pilot uses this page to require an equitime 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 from the DATA INDEX page :
[1L] A/C TO
and (blue)
[3L]
Displays reference waypoint 1.
Displays reference waypoint 2.
Note: Origin and destination airports are used by default for respective reference points 1 and 2,
until a pilot entry is made.
[1R] BRG/DIST/UTC
and (TIME)
This field displays the bearing, distance, time, from the aircrafts' current position to the
reference waypoint 1.
Idem for the reference waypoint 2.
[3R] (green) BRG : Displays the current great-circle bearing from the aircraft's position to the
reference waypoint.
DIST : Displays the current great-circle distance from the aircraft's position to the
reference waypoint.
TIME : Displays the predicted time to the reference waypoint (computed using the
current wind or a wind vector, entered by the crew).
Time is only computed in the cruise phase. In other cases, it is dashed.

Continued from previous page
[2L] and [4L] TRU WIND
and (blue)
The pilot may enter the wind (direction/velocity) at the reference waypoint and the CRZ
FL :
This wind is used to compute the time from the aircraft's position to the reference
waypoint, and to locate the equitime point.
If no entry is made, the wind/velocity field will read zero.
[2R] and [4R] EPT TO
XXX and (green)
This field displays the bearing distance and the time from the equitime point position
(ETP) to the reference waypoint.
[5R] ETP LOCATION This field displays the ident of the next waypoint following the equitime point. It provides
the distance along the flight plan from the equitime point to the indicated waypoint.
[6L] - [6R] A/C TO
(ETP) DIST/UTC
(green)
This field displays the distance and time from the aircraft's current position to the equitime
point along the flight plan.
If at least one reference waypoint exists, but no equitime point exists, the field is blank
and NO ETP is displayed in 6L.
Note: The assumptions for the equitime point computation include the cost index, speed managed
(with SPD LIM), and winds.
In case of engine-out, the EO LRC speed is considered.
PRINT FUNCTION PAGES
Applicable to:
The PRINT FUNCTION pages enable the crew to print the data relative to the current flight. This data
comes from 2 different sources :
‐ ACARS uplink messages, and
‐ Active data from the current flight.
The pilot may access these pages from the “DATA INDEX” page1/2 by pressing the [ 6R ]
ACARS/PRINT FUNCTION key.
PRINT FUNCTION PAGE 1/2
This page displays the status of the automatic printing capabilities, for the uplink messages (left
column), and the status of the manual printing capabilities of the current active data (right column).
