the MCDU, it is displayed on the FMA when
the aircraft is within 200 NM of the
destination.
The last column shows the automatic modes:
• Line 1 : Autopilot mode: AP1 for the first
autopilot, AP2, for the second autopilot,
AP1+2 for both.
• Line 2 : Flight Directors: 1FD for the
captain FD, FD2 for first officer FD, 1FD2
for both.
• Line 3 : Autothrust status: A/THR is
displayed in blue if autothrust is armed, in
white if autothrust is engaged.
The crew should always look at the FMA to
know the autothrust status. The A/THR
light on the glareshield turns on when the
autothrust is armed or engaged. Only the
FMA shows the true autothrust status.
ND – NAVIGATION DISPLAY
The ND is designed to show the aircraft's
position as it flies along the programmed
flight plan.
Typical ND in rose mode.
Tyypical ND in arc mode.
If no IRS is aligned, the ND looks like this :
EFIS
Airbus Series Vol.1
40 For Microsoft Flight Simulator use only. Not for use in real aviation.
Rose mode.
Arc mode.
EFIS Control Panel
The ND can be used in different modes as
selected on the EFIS Control Panel located on
the glareshield.
This control panel is composed of 5 selection
pushbuttons that are used when the ND is in
NAV, ARC or PLAN mode to show/hide
elements in the aircraft’s vicinity :
1. Constraint pushbutton (CSTR) : This
button is used to show/hide constraints on
waypoints on the waypoints where a
constraint is defined. A waypoint that has a
constraint is drawn with a magenta circle.
Its altitude and/or speed constraints are
displayed with numbers.
2. Waypoint pushbutton (WPT) : Show/hide
the intersections on the ND. The
intersections are represented as magenta
triangles.
3. VOR/DME pushbutton (VOR.D) : Show/hide
the VOR, DME or VOR-DME.
4. NDB pushbutton : Show/hide the NDB stations
(non-directional beacons), represented as
magenta circles.
5. Airport pushbutton (ARPT) : Show/hide the
airports, drawn with magenta stars. The
departure/arrival airport is drawn as a
white star, until the departure/arrival
runway is defined.
Only one pushbutton can be selected. When
the pilot presses one of them, the others are
deselected. If he presses a selected button,
the function is turned off.
The EFIS control panel also has 2 rotating
knobs :
6. Mode selector : ILS, VOR, NAV, ARC or PLAN.
It lets the crew select the ND mode,
explained later in this section.
7. Range selector (from 10 to 320 NM) : It lets
you select the ND range.
The EFIS control panel also selects the navaid
information displayed on the ND :
8. Left navaid selection: It can be set to ADF,
VOR or nothing. The left navaid information
is displayed on the ND bottom left corner.
9. Right navaid selection: It can be set to ADF,
VOR or nothing. The right navaid
information is displayed on the ND bottom
right corner.
ND Modes
ILS Mode : The ILS needle is displayed in
magenta with the course deviation indicator
and the glideslope indicator. The ILS name,
course and frequency are displayed in the top
right corner. TCAS information is visible.

VOR Mode : The VOR1 needle is displayed in
blue with the course deviation indicator. The
VOR1 name, course and frequency are
displayed in the top right corner.
TCAS information is visible.
NAV Mode : The flight plan entered in the FMGC
is displayed in ROSE mode. The next waypoint
name, bearing, distance and estimated time of
arrival (ETA) is displayed in the top right
corner. TCAS information is visible.
ARC Mode : The flight plan is displayed in ARC
mode. The next waypoint is displayed in the top
right corner like on NAV mode. In this example,
the surrounding waypoints are also displayed
(the WPT button is lit on the EFIS CP).
PLAN Mode : The flight plan is displayed. The
reference waypoint displayed in the center is
the waypoint selected on the second line of the
MCDU Flight Plan page. You can visualize the
entire flight plan by scrolling the waypoint on
the MCDU FPLN page.
General Information
The ND also shows permanent information
that appears in all modes except PLAN mode.
1. Ground Speed (GS) : This is the aircraft’s
speed relative to the ground. This
information is visible only when at least
one of the IRS is aligned (if you are in
Beginner mode, the IRS are always
