vertical deviation with respect to the FM theoretical
vertical flight plan (F-PLN).
Landing field elevation is also indicated by a blue
horizontal bar on the altitude scale.
NOTE: The Flight Management (FM) guidance is
associated to the Flight Guidance (FG) modes
(NAV, CLB, DES).

EFIS DISPLAY
FLIGHT MANAGEMENT (FM) DISPLAY ON ND
The Navigation Display (ND) works in five different
modes selected on each Electronic Flight Instrument
System (EFIS) control panel of the Flight Control Unit
(FCU).
In ROSE-NAV, ARC and PLAN modes, the ND displays the
flight plan computed in the FM part at a scale defined
by the range selected on the EFIS control panel of the
FCU.
The ND represents basically: the aircraft position,
the flight plan data, the range selected on the FCU
and autotuned navaids.
NOTE: The aircraft position is fixed in all display
modes except in PLAN mode where it moves along
the flight plan.
There is correspondance between the flight plan
displayed on the ND and the MCDU flight plan (F-PLN)
page if no scrolling has been done on this page.
The TO waypoint is displayed in white, the rest of the
flight plan line and waypoints being displayed in
green.
The TO waypoint characteristics are displayed at the
top right hand corner of the ND:
- ident (in white) and bearing (in green),
- distance to go (in green),
- Estimated Time of Arrival (in green).
A crosstrack deviation, if any, is also provided, in
green, on the left or right hand side in nautical
miles.
NOTE: Wind speed and direction, Ground Speed (GS) and
track are computed by the FM part and transmitted
to the Display Management Computers (DMCs) which
also receive the same data from the Air Data and
Inertial Reference Units (ADIRUs).
Radio navaids are displayed in cyan when they are
autotuned by the FM part.
Specific symbols can appear, along the flight plan,
corresponding to some maneuvers such as Start of Climb
(S/C) in white, Top of Climb (T/C) in cyan, Top of
Descent (T/D) in white, holding pattern and turn
procedure.

DATA BASE DISPLAY P/Bs
By pressing these five interlocked pushbuttons (WPT,
VOR.D, NDB, ARPT and CSTR), different information from
the navigation data base is available and will be
displayed in magenta.
Note that these options are exclusive and the priority
is given to the last which has been selected.
When the WPT pushbutton is pressed, all waypoint
locations in the related range are transmitted to the
ND to be displayed.
When the VOR.D pushbutton is pressed, all VOR and/or
DME stations locations in the related range are
displayed on the ND.
When the NDB pushbutton is pressed, all Non Directional
Beacon station locations in the related range are
transmitted to the ND to be displayed.
When the ARPT pushbutton is pressed, all airport
locations available to the aircraft, in the related
range, are transmitted to the ND to be displayed.
When the CSTR pushbutton is pressed, all speed and
altitude constraints (if any) on one or several
waypoints, are transmitted to the ND to be displayed.
For example, the constraint on the BGN waypoint are:
- an altitude at or below the flight level 180,
and
- a speed at or below 250 kts.
