Airport Surface Charts
Airport surface charts provide a graphical presentation of
the airport surface area (runways, taxiways, buildings,
towers and other objects), within the immediate airport
vicinity.
From either the Custom Map or the IFR en route Map,
airport surface charts will automatically be loaded and
displayed as an overlay if the following conditions are met:
·
The airport surface chart is within the loaded
database
·
The airport surface chart is geo-referenced by
Jeppesen
·
Airport Chart menu layer is turned on
·
The aircraft position is within the coverage of the
chart
·
A loaded chart is not being “flown”
In typical operation, the above conditions are met when
the unit is turned on, meaning that the airport surface
map is displayed as soon as GPS position is acquired.
Note that the Zoom Scale Auto-Transition feature
determines the initial zoom scale that is set when the
aircraft is on the ground, which is important when
working with surface charts.
Viewing Surface Charts
The airport surface charts are treated similarly to
approach type charts in that they can be viewed through
both the Chart View Function and on the Custom
Map/IFR Map as an overlay. However, as there is only
one unique surface chart for a given airport, it does not
need to be manually loaded for display. The nearest
available airport surface chart will always be used. When
viewed from the Chart View Function, the airport surface
chart shows up as the first available chart for the selected
airport of interest. Thus, after selecting the airport of
