AUTONAV
AutoNav allows the AV8OR to automatically switch between the
external and internal GPS sources when there is more than one
source. AutoNav is enabled in the Navigation Setup Page. See
the Navigation Setup section on page 2-153 for setup instructions.
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.
•
The following warning message is displayed that requires pilot
confirmation.
•
“The external GPS source is no longer available. The GPS
source has been changed to the internal GPS backup. GPS
limited to VFR use only. PRESS OK TO ACKNOWLEDGE”.
•
Touching the OK soft key closes the message window.
•
If the external GPS source becomes valid again for a period of
more than 5 seconds, the AutoNav function automatically
switches back to the external GPS source.
•
The following warning message window is displayed that requires
pilot confirmation.
•
“The external GPS source is now available. The GPS source has
been changed to the external GPS source. PRESS OK TO
ACKNOWLEDGE”.
•
Tapping the OK soft key closes the message window.
