STAR) and when a ight plan Discontinuity exists between waypoints.
Flight Plan waypoints
The waypoints forming the ight plan are drawn as diamonds. The active (“TO”) waypoint is shown in white, and all others
are in green.
If a waypoint has associated constraint, a circle is drawn around it. Circle is magenta if the aircraft follows ight plan and obeys
the constraint, and white if aircraft is not following the plan (ying a selected heading). Waypoint constraints can be viewed on
ND by pushing CSTR button on EFIS control panel.

Pseudo waypoints
During vertical ight prole calculation, the FMS automatically inserts Pseudo Waypoints into ight plan. These waypoints represent
points on ight plan route where aircraft will start climb or descent or will level off. They are displayed on ND as follows:
Level off: A point where the aircraft will level off at altitude constraint
or at cruise altitude (Top of Climb). Constraint level-offs are drawn in
magenta, TOC is in blue.
Top of Descent: A point where descent from cruise altitude should start.
Symbol is white before descent mode is armed, and is blue then
descent is armed.
Speed change: A point where the aircraft will automatically accelerate
or decelerate to meet speed constraint or speed limit.
DECEL: Deceleration point is automatically inserted before approach
segment. Overying this waypoint will engage Approach ight stage and
aircraft will automatically decelerate to approach speed.

Airports and runways
Origin and destination airports and runways are depicted on ND in white
color. If a runway is not selected, and asterisk with airport identier is
displayed.
When a runway is specied, it is drawn to scale and properly oriented, and
labelled with airport ID and runway name.

‚ TO waypoint info
Information on active (TO) waypoint is displayed in the upper right corner. The information includes:
• Waypoint name,
• Bearing to waypoint,
• Distance to waypoint,
• Estimated Time of Arrival (ETA) at TO waypoint.
ƒ Database Map
ND can display a moving map of database navaids, waypoints or airports by pushing corresponding button on EFIS control panel.
Selected button is indicated by a light. Only one type can be selected at a time. Second push on lighted (selected) button removes
the map display. Displayed symbols are magenta.

„ TCAS contacts
Trafc Alert and Collision Avoidance system utilizes transponder returns from other aircraft. It determines range, bearing, and
relative altitude of other aircraft and displays a map of aircraft contacts on ND.
An aircraft is represented by a white diamond. If contact is at different altitude
than own ship, the altitude difference, in 100s of feet, is displayed above or
below the symbol. If contact aircraft is climbing or descending, an arrow is
drawn beside the symbol to indicate this. In the example, the left aircraft is
2000 feet above and ies level, and the right aircraft is 500 ft below and is
climbing.
Displayed is the trafc at up to 40 nm distance and within 2700 feet vertically.
Trafc alerts and advisories are not modelled.

ARC Mode
ARC mode is similiar to ROSE NAV mode, and is the most used mode. It displays the same information as ROSE NAV mode, but
own aircraft symbol is shifted to the bottom of the display and displayed is forward sector ahead of the aircraft. This gives bigger
display area for controlling forward space while ying enroute.

PLAN Mode
The PLAN mode allows the pilot to preview future portions of ight plan not displayed in ROSE NAV or ARC mode. In PLAN mode,
the display is north-oriented and displays a full compass scale with true north at the top.
The PLAN mode displays ight plan in similiar way to ROSE NAV or ARC modes, but centers the display on waypoint visible
on line 2 of MCDU F-Plan mode (or next line, if line 2 contains a pseudo waypoint or ight plan discontinuity). The pilot can
