interest, the list of charts will have an “Airport” entry as

the first item in the list. As with standard approach charts,

when viewed from the Chart View Function, the aircraft’s

ownship position is not shown on the airport surface

chart.

If an approach chart is currently loaded and being

displayed (aircraft is in the air), it will take priority over

displaying the airport surface chart. Once the aircraft

touches down and the speed drops below the air/ground

threshold, it is assumed that a missed approach procedure

is not needed. At this point, the approach chart is

un-loaded and the airport surface chart is displayed.

While on the ground, airport surface charts will take

priority over any loaded approach chart.

Operational Considerations

When to Load a Chart

An approach chart can be loaded at any point during the

flight, including on the ground before takeoff. Note that

the approach will not be shown on the map itself until the

aircraft’s speed is above the air/ground speed threshold.

The approach will be automatically un-loaded when the

aircraft’s speed goes below the air/ground speed threshold.

Flying an Approach

It is important to recognize that the charts function is not

intended to provide guidance information for flying an

approach. Its intended function is to provide basic

situational awareness as to your current position relative

to the approach as a whole. Standard instruments MUST

be used to actually provide the navigational information

required under IFR conditions.

Approach to Surface Map Transitions

Logic is incorporated that will automatically transition the

display from an in-flight approach chart display to a

zoomed in view of the airport surface chart upon landing.

The intent is to provide a hands-free transition from the

approach phase of flight to the airport surface navigation
