Requires 35 seconds of continuous transmission. Verify the
PTT is stuck and contact a dealer for service as required.
Transmitter Fault, no TX ability
Transition to a backup VHF com radio (if available) or
initiate lost communication procedures. Contact the Avidyne
Service Center or a dealer for service.
Configuration Error – IFD Requires
Service
The IFD has encountered an internal error while determining
the system configuration. Contact the Avidyne Service
Center or a local dealer for service.
Negative climb rate or altitude loss
TAWS NCR algorithm has determined corrective action
should be taken immediately.
The GPS has stopped providing a navigation solution. If
GPS is the only navigation solution source available, then
expect degraded IFD operation (e.g. no map, no FMS
guidance, etc.)
