This field displays dashes when the descent or approach phase is active.
OPT This field displays the optimum flight level (in green), that is computed based
on the current gross weight, cost index, temperature, wind and a minimum
estimated cruising time of 15 min. It displays dashes :
In cruise, when the aircraft is less than 15 nm from the Top of Descent‐
In the descent and approach phases‐
If an engine‐-out is detected.

REC MAX This field displays the recommended maximum altitude (in magenta), that is
computed based on the current gross weight and temperature.
It provides the aircraft with a 0.3 g buffet margin, a minimum rate of climb
at MAX CL thrust, and level flight at MAX CRZ thrust. This field is limited to
FL 410.
If one engine is out (or two engines for A340 aircraft only), this field displays
the recommended maximum engine-out altitude, that is computed based on
the long-range cruise speed and assuming that anti-ice is off.
[ 2L ] REPORT This key calls up the REPORT PAGE.
[ 2R ] VDEV This field is displayed during the descent and approach phases, when NAV
mode is engaged, or in HDG mode, provided that the crosstrack error (XTK)
is less than 5 nm. It displays the vertical deviation between the aircraft’s
current altitude and the FMS-computed vertical profile.
Line 3 UPDATE AT The flight crew can update the FMS position via this field by entering either
the ident of a waypoint, a NAVAID, an aiport, a latitude and longitude (L/L), a
place/bearing/distance (PBD), or a place-bearing/place-bearing (PB/PB).

Line 3 UPDATE AT When the flight crew has entered this data, this field changes its format to :
“CONFIRM UPDATE AT”, followed by the latitude/longitude and ident of the
inserted position with an asterisk.
Note: If no ident has been inserted, the field displays “ENTRY” instead of
an ident.
The flight crew presses the right-hand key adjacent to the asterisk to confirm
the update, when the aircraft overflies the inserted position.
Line 4 BRG/DIST On this line the flight crew can enter an airport, a waypoint, a NAVAID,
or a runway. The flight crew may enter this information as an ident,
a latitude/longitude (L/L), a place/bearing/distance (PBD), or a
place-bearing/place-bearing (PBX). The field then displays the FMS
computed bearing and distance of this bearing from the aircraft’s present
position. If it does not have an ident, the point is called “ENTRY”.
Example : BRG/DIST
340°/95.4 to ENTRY
The line displays a T if the true reference is selected
(NORTH REF pushbutton switch).
[ 5L ] PREDICTIVE
GPS
This field provides access to the PREDICTIVE GPS page.
[ 5R ] GPS PRIMARY
If installed, this field displays GPS PRIMARY when the GPS PRIMARY is
available. When GPS PRIMARY is not available, this field is blank.
The scratchpad displays “GPS PRIMARY″ when GPS/IRS becomes
available or “GPS PRIMARY LOST” when GPS/IRS is no longer available.
[ 6L ] REQUIRED This field displays the default value for the required navigation accuracy. The
flight crew can modify it, as necessary. If the flight crew has not modified this
data, the default value changes according to the current flight area (Refer to
99 Duref Cible FCOM).

ACCUR HIGH/LOW This field displays the navigation accuracy estimated by the FMS.
HIGH indicates that the estimated navigation accuracy is high : The
ESTIMATED value is less than the REQUIRED value. LOW indicates that
the estimated navigation accuracy is low : The ESTIMATED value is greater
than the REQUIRED value.
[ 6R ] ESTIMATED This field displays the current Estimated Position Error value (EPE), as
computed by the FMS.
