My transponder expired a month ago. There is no shop at where my aircraft is currently kept, so I need to fly to an airport 20 minutes away to a shop. What procedure should I follow?
- Call ATC when airborne to request a deviation? Or do I need to file some application with FAA/FSDO beforehand?
- Which ATC to call? I am at a private uncontrolled airfield now, but I am under Mode C veil. The airport I am flying into is Class D and has an ATC. Shall I call them?
- Shall I keep the transponder on during the flight? Or shall I keep it off? For that matter, if I simply flew the short flight with it on and said nothing, how would anyone find out that it is expired?
