Different symbols are used to distinguish between waypoint types. The identifiers for any on-screen
waypoints can also be displayed (by default the identifiers are enabled). 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 following symbols are used to depict the various airports and navaids on the Map page:
Airport with hard surface runway(s); Primary runway shown
Airport with soft surface runway(s) only
Private Airfield

The map display can be set to 23 different scale settings from 500 feet to 2000 nautical miles (statute
and metric units are also available). The scale is indicated in the lower left-hand corner of the map
display, and represents the top-to-bottom distance covered by the map display.
To select a map scale:
1. Press the up arrow side of the RNG key to zoom out to a larger map area.
2. Press the down arrow side of the RNG key to zoom in to a smaller map area and more detail.
An autozoom feature is available which automatically adjusts from an en-route scale of 2000 nm
through each lower scale, stopping at a scale of 1.0 nm as you approach your destination waypoint. The
autozoom feature is turned on/off from the map setup page described on page 29.
The Map page also displays a background map showing lakes, rivers, coastlines, highways, railways
and towns. When a map scale is selected below the lower limit at which the map detail was originally
created, an "overzoom" indication appears on the map display, below the scale reading. "Overzoom"
indicates that the detail at this scale may not accurately represent actual conditions (and extra caution
should be observed when these scales are used for navigation).
