When the cursor is over the heading you wish to alter, move the joystick to the right. This will in turn
move the cursor over to the set of options available for that heading. Moving the joystick up and down
will then allow you to scroll through these options.
The various settings available for each heading are listed below. The default settings are those shown
in the illustration above. To reset the values on this Screen (or Screens 22A, 22B and 22C) to their
defaults, press Key 3 RESET VALUES. This will reset the values on the displayed screen only. In
order to reset all user defined data globally, see the Clear Memory screens later in this section.
Settings available:
ORIENTATION: track up / north up.

ORIENTATION: This allows you to choose whether to have the map displayed with north at the top of
the screen or orientated to have the aircraft's track aligned up the screen.
AIRPORT NAMES: This gives you the option of labelling the airport icons on the map with the full
names of the airports (long ones truncated to 9 characters), the full names of the city associated with
the airport or the ICAO 3 or 4 letter location indicators.
MAP UNITS: This allows you to specify the units in which the scale bar and all navigation information
will be displayed. If nautical or statute miles are selected, all lengths and altitudes will be reported in
feet. If kilometres are selected, all lengths and altitudes will be reported in metres.
COORD SYSTEM: This option controls whether the unit operates with reference to Latitude/Longitude or
UTM or OSGB grid references
DISPLAY: Here you can choose the orientation of the display with respect to the keys. Portrait Std
mode is usually selected for leg and yoke-mounted operation.
LANGUAGE: This is self-explanatory; it enables you to choose the language in which you would
prefer the unit to operate.
MIN R/W LENGTH: This allows you to set the minimum length of main runway at the airports, which
will be displayed when you ask the unit to display the ten nearest airports. The minimum length can be
specified in steps of 1 foot from 0 to 15,000 feet. By setting a minimum length you can force the unit to
search for and display only airports with runways, which are equal to or longer than the pre-set
minimum length.
R/W SURFACE REQUIRED: R/W Surface Required is also used when searching for the ten nearest
airports in map mode. If set to hard/soft, airports with either hard or soft runways will be displayed. If
set too hard, only airports with hard runways will be displayed and soft-runway airports ignored.
