Detailed Operation
Loading the Approach Chart
Once the airport is selected, the individual approach chart to be overlaid can be loaded from a list of geo-ref-
erenced approach charts available for that airport. Not all approach charts can be overlaid in this fashion and
only geo-referenced charts will be presented for selection from the Custom Map. Because of this, it is possible
that approach charts that are viewable under the Chart View Function may not be presented in this list.
NOTE: The pilot must be aware that not all charts in the loaded database can be used as an
overlay.
Once the approach chart is loaded, a green Annunciator will illuminate at the top of the screen indicating the
airport name and specific chart that has been loaded.

Viewing the Chart as an Overlay
Display of Coverage Area
Once the desired approach chart has been loaded, a green Annunciator bar with the approach name is illumi-
nated at the top of the Custom and IFR maps. If the aircraft is outside the coverage area of the approach chart,
a black rectangular box will be presented that shows the coverage of the chart itself.
Once the aircraft has entered the coverage area, the chart contents will be displayed on the screen. Note that
a loaded approach chart is only viewable from the maps when the aircraft is in flight, otherwise, the airport
surface chart has priority and the approach chart must be viewed from the Chart View function.
