Gravity (ZFWCG) values, as entered before engine start on the INIT B
page. The flight crew can re-enter or modify these values after engine
start on the FUEL PRED page.
If at engine start, no ZFW or ZFWCG values have been entered, amber
boxes are displayed in the corresponding field. The flight crew must
enter the ZFW/ZFWCG values (as appropriate) to obtain a speed
profile and predictions.
[ 5R ] MIN DEST FOB
(green)
Displays the Minimum Fuel at Destination. It allows the flight crew to
specify a minimum FOB value required at destination. By default, it is
equal to the FINAL + ALTN fuel. This field cannot be modified.
[ 6R ] CRZ TEMP/TROPO
(blue)
Displays the temperature at the cruise flight level, and the altitude of the
tropopause.
The flight crew can modify both values.
This field is dashed, when the aircraft sequences the top of climb.
Note: All fields, except [ 6R ], are dashed before engines are started.
FLIGHT PLAN PAGES
Applicable to:
,
,
MSN,,
4538,,
GENERAL
These pages display all active and alternate flight plan, waypoints along with the associated
predictions.
The flight crew can make all revisions to the lateral and vertical flight plans from these pages:
The flight crew presses the left key to revise the lateral flight plan, and the right key to revise the
vertical flight plan.
The flight crew presses the F-PLN key on the MCDU console to access page A of the active
flight plan.
FLIGHT PLAN A PAGE
Page A displays time, speed, and altitude predictions for each active flight plan waypoint.

TITLE FLIGHT NUMBER (blank, if no flight number has been entered).
This line may display OFST in white, if a lateral offset is flown.
Line 1 to Line 5 WPT, UTC,
SPD, ALT
These lines display consecutive waypoints, alongwith associated
predictions of time, speed or Mach and altitude for each.
TIME is displayed before takeoff, and UTC after takeoff. After the pilot
enters an Estimated Takeoff Time (ETT), UTC is displayed.
The time and flight level display at the FROM waypoint (first line of
the flight plan) are values that the system memorized at waypoint
sequencing.
[ 1R ] SPD/ALT The field dedicated to SPEED or MACH is blank at the FROM
waypoint, except at the departure airport. (V1 associated with runway
elevation, is displayed).
Note: When the HOLD marker is slewed, the HOLD SPD label will overwrite the TIME/UTC
title. In addition, the IMM EXIT or RESUME HOLD prompt will replace the SPD/ALT field.
Line 6, DEST UTC/TIME
DIST, EFOB
DIST is the distance to destination along the displayed flight plan.
EFOB is the estimated fuel on board at destination. The EFOB at
destination will turn to amber, if it becomes less than the MIN DEST
FOB value.
The sixth line is permanent and is displayed in white font, once
predictions are available, except when a TMPY F-PLN is displayed,
or in some cases when an ALT CSTR is entered (“← CLB or DES →”
prompt appears).
Note: The predicted altitude at a waypoint is related to the QNH below the transition altitude,
and is given as a flight level above the transition altitude.

The generic flight plan page displays the FROM waypoint (last waypoint to be overflown) on the
first line, and the TO waypoint (in white) on the second line. The FROM/TO flight plan leg is called
the active leg.
The flight crew can use the scroll keys to review all flight plan legs down to the last point of the
alternate flight plan. The AIRPORT key serves as a fast scroll key. The pilot can press it to call up
the next airport (DEST, ALTN, ORIGIN) to be displayed on the flight plan page.
In order to return to the beginning of the flight plan page, the pilot presses the F-PLN key on the
MCDU console.
The display shows the name of the leg between two waypoints, and the distance between them on
a line between the lines that identify them. During an approach, this in-between line also defines
the angle of the final descent path. For example, “2-3 °” indicates that the leg is two nautical miles
long, and the flight path angle is -3 °.
The display shows the bearing between FROM and TO waypoints as the bearing from the aircraft
