Selectable GPS Data Source
The AV8O
R system can receive data from either the internal or an
external GPS Source. When an external source is configured, the
unit uses data from it. Switching to the internal GPS source is
automatic when data from the external source is no longer valid or
available.
AUTONAV
Whe
n enabled, AutoNav allows the AV8OR to automatically switch
to the internal GPS source when the external source is unavailable
or has failed.
The AutoNav function is not enabled until both the internal and the
external position source have acquired a valid satellite fix or the Go
Fly program has been running for 4 minutes.
If the external position source is invalid for more than 5 seconds, the
Go Fly program will switch to the internal GPS antenna.
The following sequence of events occurs:
• If the flight plan source is the external GPS, then the flight
plan is captured and cross-referenced to the internal
database.
