Map Mode Screens
The box marked POS: will display your present position as a distance
and cardinal bearing from the nearest item in the database. The geo-
graphical item used to describe your position to you is chosen on the
basis of the POSITION REF: setting on Screen 22, Map Customization
Screen.
If you have chosen VORs as the position reference on Screen 22, your
position will be reported as a distance (range) and bearing from the
nearest VOR. If you have chosen VORs & AIRPORTS as the position
reference on Screen 22 and your position is within 5nm of a VOR, your
position will be reported as a distance and bearing from that VOR even if
there is an airport nearer (i.e. VORs have priority). If there is no VOR
within 5nm then your position will be reported with respect to the nearest
VOR or airport with no priority being given for either.
If you have chosen ALL DATA as the position reference on Screen 22,
your position will be reported against a table of priorities. If your position
is within five miles of an airport, it is your distance and bearing from that
airport that will be displayed, even if there is a navaid, user waypoint or
town nearer. All airport names are shown preceded by an asterisk
character (*) in order to distinguish them from towns or cities with
similar names that may have significantly different locations. If your
position is found to be within five miles of a VOR beacon and more than
five miles from an airport, then your position will be shown with respect to
the VOR beacon, even if there is a user waypoint, NDB or town nearer.
User waypoints have next priority followed by NDBs and towns last.
At the bottom left hand corner of the display you will also see a Scale Bar
showing a measurement. The measurement may be in nautical miles,
statute miles or kilometers depending on the map units, which you have
selected from Screen 22. Map Customization Screen.
Pressing Key 4 will take you to Screen 41, the NAV Menu Cover Screen.
Pressing Key 5 will take you to Screen 13 from which you can select a
DIRECT TO destination.
Under normal circumstances, you will not see any joystick pointer on
Screen 38. However, if you do move the joystick, a pointer will appear
just beside your present position icon and the display will change to
Screen 39.
