Hi,
first I would need to know what type of aircraft You want to be in; in jetliners for example most headsets use 3-pin XLR connectors; I don't know about the wiring but with three pins only there is nopt much room for mistakes. If You use the observer's headset You can also record the pilots conversation via intercom and You can adjust the volume individually.
I would make sure that the camcorder has 2.5 mm jacks as all models I know have 3.5mm jacks.
What kind of equipment do You use ? I used a manfrotto suction plate to mount the camcorder to the side window, it worked well.

This Airbus is o.k., but why did it come with a RENAULT key ??
