ND - Navigation Display
The ND is the main instrument for navigation. It displays the route
programmed in the FS2002 GPS system, the navaids and airports located around the
aircraft, and also includes a TCAS system that shows all the other aircrafts
flying around, with potential alerts if they are too close.
The ND has 5
display modes: LS, VOR, NAV, ARC and PLAN.

Description of the different pars of the ND:
|
Navaid and Airport Display
The ND shows all the airports and navaids around the aircraft, depending on the range and on the visibility buttons located on the EFIS control panel. They are shown with various symbols, with their name, and the frequency is displayed if the corresponding option is selected on the MCDU. For airports, the frequency displayed here is the ATIS frequency, if available.

Intersection |
If an ILS frequency is set, a dashed line is drawn on the ND to show the ILS course and to help for establishing on the localizer.
Route display
The route programmed in the GPS system is shown on the ND, with all its
waypoints. The departure waypoint is shown with a magenta square, and the
arrival waypoint (the last) is shown with a magenta circle.
If the Heading is
managed on the FCU (which means the auto-pilot will
follow the route programmed), the route is displayed in green. Otherwise, it is
drawn is yellow.
Navigation
The main part is the center part. Depending on the selected mode, the display will change and various elements may be visible or not.
|
LS mode (Rose) This mode is dedicated to ILS aproach and landing. It displays the ILS
course and localizer deviation. In the top right corner, the name
and course of the selected ILS are displayed. |
|
VOR mode (Rose) This mode is designed for optimal VOR/ADF usage. The top right corner
contains the closest VOR station information: type, frequency, course
and name. |
|
NAV mode (Rose) Used for navigation, it shows all the necessary information is rose mode. The top right corner contains information about the next waypoint of the route: name, bearing, distance and ETA (estimated time of arrival). |
|
ARC mode (Arc) This mode is similar to the NAV mode, the only difference is the Arc
representation. This is the most common mode used by the pilots during the
flight. |
|
PLAN mode This mode is specific to the route visualization. Only the programmed route is displayed with all the waypoints. The waypoints shown in the center of the display is the waypoint selected on the MCDU. By selecting the next waypoint on the MCDU, you can visualize the whole route, waypoint by waypoint. This display is NORTH-oriented. |
TCAS
The ND shows information about all the aircrafts flying around you. Each
aircraft is represented by a diamond, and the numbers show the altitude
difference (in hundreds of feet). For example, +50 indicates the aircraft is
flying 5000 feet above your current altitude.
In normal situation, the
aircrafts are drawn in grey. If an aircraft is too close from you, it is
displayed in orange to indicate a collision danger. If it is VERY close from
you, a TRAFFIC alert is triggered, you will hear it...

Aircrafts in normal situation: the distance and altitude separation are correct. |

Danger of potential collision: this aircraft is close and the altitude difference is only 500 feet !! |
