WAYPOINTS
Off-route waypoints are also displayed on the map display, and these can include
user waypoints or International Civil Aviation Organization (ICAO) waypoints from
the active FMS database.
Up to 10 ICAO waypoints can be displayed on the map display at a time; if there are
more than 10 ICAO waypoints within the current map display range, the 10 nearest
to the aircraft are displayed.
CURRENT RANGE
The current map display range is shown at R3 and R4 with the caption RNG on the
compass rose, arc and rose plan page. Pressing R3 and R4 cycles the display
through the available range options 5, 10, 20, 40, 80, 160, and 320 nm.
Map Display Control
The line select keys are provided to control the NAV compass rose and ARC
displays to allow the pilot to change some of the information displayed or to allow
access to NAV sub-pages.
MAP DISPLAY DATA
The map display data can be managed by pressing L4 labelled DATA. This displays
the associated sub-page where the pilot can remove, by toggling on or off, a
selected off-route waypoint from the display.
These waypoint types include airports (AIRPORT), waypoints (USER WPT), VHF
navaids (NAVAID), and non-directional beacons (NDB).
NAVIGATION INFORMATION DISPLAY AND SOURCE SELECTION
The navigation information display is located to the left of the map, with the
navigation source aligned at L3 and the navigation information directly above at L2.
Selection of the navigation source is accomplished by pressing L3, which cycles to
the next available navigation source, rotating through the available sources with
each successive button press. The selected source is displayed as OFF, FMS,
VOR/LOC, or blank.
The navigation information is displayed in three lines, with the content of the lines
depending on the selected navigation source. L2 has functions in addition to the
display of the navigation information.
