DETAILED OPERATION
MAP MODE SCREENS
Screen 38: Basic Map Mode Screen
Pressing MAP in Main Menu will access this Screen. When you enter this Screen, if the
Skymap IIIC's internal GPS receiver has been able to establish a fix or if the external GPS
you are using to feed your Tracker IIIC is sending valid data, a Screen similar to the above
will be displayed. The map is initially displayed at the Zoom Level where the Scale Bar
represents 8nm. This is approximately the same scale as a 1:500,000 chart. If there is no
valid GPS fix data available, the words NO FIX POSSIBLE will be shown across the centre
of the screen in a box. If the fix is lost at any time during normal operation of the unit, the
same NO FIX POSSIBLE box will be overlaid on the map. For an External GPS source the
additional messages NO EXTERNAL POSITION DATA and INVALID EXTERNAL
POSITION DATA may be displayed in place of NO FIX POSSIBLE.

The map will be shown in either North Up mode or Track Up mode depending upon the
setting you have made from Screen 22, Map Customisation Screen. The displayed data
will be updated every second. From this page, if you press Key 1, Screen 2 Main Menu
will take its place. You can use Keys 2 and 3 at any time to zoom the map in and out to
whichever one of the twelve pre-set scales you wish to use. The levels of detail appearing
at each zoom level can be selected on Screen 22A/B or C, described in the Setup Screens
Section of this Manual. If you want to zoom in or out by more than one step at a time, you
can apply multiple presses to Keys 2, ZOOM IN, and 3, ZOOM OUT, whilst watching the
scale bar calibration figure and the ZOOMING message box.
The small boxes marked TRK: and GS: display your present track and ground speed.
Ground speed is displayed in the units selected on Screen 22, Map Customisation Screen.
Track will be magnetic (i.e.: true with local variation automatically taken into account).
The box marked POS: will display your present position as a distance and cardinal bearing
from the nearest item in the database. The geographical item used to describe your
position to you is chosen on the basis of the POSITION REF: setting on Screen 22, Map
Customisation Screen.
If you have chosen VOR’s 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
VOR’s & AIRPORTS as the position reference on Screen 22 and your position is within
5nm of an airport, your position will be reported as a distance and bearing from that airport
