Instrument Flashcards
Lost Comms in IMC
Step 1: Route - select first able to comply with
- Assigned
- Radar Vectors
- Expected
- As Filed
Step 2: Altitude - select highest
- Minimum IFR altitude
- Expected
- Assigned
Step 3: Arrival at your clearance limit - if IAF
- yes - decent and approach started as close as possible to EFC or ETA
- no - if cleared to destination airport
- over fly airport - leave limit as close to EFC and fly to a fix where approach begins when the aircraft arrives over your clearance limit, start decent as close to ETA
- if can’t over fly airport - use best judgment on how to proceed to fix start approach as close to ETA - if early hold as depicted lose altitude in hold if needed approach as close to EFC/ETA
Step 4: Submit NASA ARC Form 277(b)
Troubleshoot possible lost comms
- check frequency
- check ammeter, if required follow appropriate electrical malfunction checklist
- ensure headset is plugged in
- check volume
- check circuit breaker
- switch radios
- switch to last frequency you were in contact with ATC on
- switch headset jack from pilot side to co pilot side or vice versa and use mic button on corresponding yoke
if not resolved
can you continue VFR
- yes - squawk 7600 - continue lost comms under VFR
- no - squawk 7600 - continue lost comms under IFR
