6-10 General
AXP322 Lost GPS Position Data
ADS-B position data had previously been valid and then
transitioned to invalid. Check the ADS-B position source.
No communication with the VHF radio
†
Transition to a backup VHF com radio (if available) or
initiate lost communication procedures. Contact the Avidyne
Service Center or a dealer for service.
No Communication with Remote
Transponder
No data has been received from the remote transponder for
greater than 2 seconds. Contact the Avidyne Service
Center if this persists across power cycles.
No position available
The IFD cannot compute a navigation solution. IFD
operation will be degraded (e.g. no map, no FMS guidance,
etc.) Transition to alternative navigation sources.
Excessive Descent Rate
TAWS EDR algorithm has determined a potential CFIT
scenario is developing - recover the aircraft.
Invalid GPS Position/Velocity
The GPS solution is lost or the GPS velocity quality
parameters dropped
below required accuracy limits. A “bing-
bong” chime is played if this condition occurs. Contact the
Avidyne Service Center if this persists across power cycles.
