Chart Views
If the currently displayed chart is not the desired one, use the
"Select Chart" LSK to jump back to the Directory List where the
desired airport/chart can be selected.
Once a chart is displayed, the left-hand LSKs provide means to
alter the view or presentation of the chart. A "Chart" LSK is
provided to select Airport or Procedure type charts. The "View"
LSK provides a set of views to choose from based on which
option was selected in the "Chart" LSK. For example, if Procedure
was picked, then one of five chart views can be selected (Plan,
Header, Profile, Minimums, All). If Airport was picked, then a
slightly different set of chart views could be selected (Plan,
Header, Runways, Departure, All) The chart can be zoomed
in/out as desired by using the right-hand knob on the IFD or via a
pinch-zoom touch method.
Taxi Charts
If a published procedure was used via the Charts tab for the
landing airport, the display chart will automatically switch over to
the airfield diagram during post-landing roll out. Your ownship
position on the airfield diagram chart will be displayed as an aid in
surface navigation.
