The map display occupies the right side of the display and shows your position
relative to nearby airports, navaids, user waypoints and airspaces. Different symbols
are used to distinguish between waypoint types. The identifiers for any on-screen
waypoints can also be displayed. Special-use and controlled airspace boundaries
appear on the map, showing the individual sectors in the case of Class B or Class C
airspace. The map display can be configured to display airports, navaids, user way-
points, airspaces only at certain scales or these items may be disabled entirely (see
page 76). This allows you to de-clutter the map display at larger scale settings.
The map display can be set to 14 different scale settings from 0.5 to 300 (nautical
miles, statute miles or kilometers). The scale represents the top-to-bottom distance
covered by the map display.
To select a map scale:
1. Rotate the
K
knob clockwise to increase the map scale and show a larger area.
2. Rotate the
K
knob counterclockwise to decrease the map scale and show a smaller area.
The autozoom feature will automatically adjust from an en route scale of 300
through each lower scale, stopping at a scale of 1 as you approach your destination
waypoint. The autozoom feature is turned on/off from the map setup page described
on page 76.
The orientation of the map may be fixed at ‘north up’, or set to ‘desired track up’
(dtk up) or ‘track up’ (trk up). The ‘north up’ setting will keep the top of the map
display fixed on north. ‘Track up’ will cause the map to rotate so the top of the map
is the direction you are heading. ‘Desired track up’ keeps the map display fixed along
your desired course. Map orientation is changed on the map setup page described on
page 76.
