Using a Real Aviation Headset with a PC Simulator

In parallel with real-world flight training I’ve begun to use a PC flight simulator more seriously. This reinforces what’s learned in the real plane and also allows me to practice flights ahead of time. The simulator is only vaguely analogous to real flying though, so the more I can do to make it realistic the better. One realism point would be to use the real aviation headset, but the headset does not directly plug into the PC. After a good bit of research cross-referencing part numbers and checking schematics, I came to two critical conclusions:

#1 – Standard 1/4″ mono audio dimensions are the same as general aviation headset plug dimensions. (The speaker plug, not the microphone plug)

#2 – The sound card output levels are compatible with the headset’s required input level. (not so low that they’d be inaudible, and not so high that they’d blow out the speakers on even the lowest setting)

Once those realizations were made it was easy enough to make an adapter cable from a scrap audio cord and a $2 1/4″ mono jack. There are ready-made adapters online, but these go for far more then even the standard 5X markup for anything with ‘aviation’ in the description; so it was worth the effort to spend a few minutes and build myself. The microphone connector is more special-purpose and would require finding the special jack and likely some circuitry to make the levels work for the PC mic input, I don’t do anything in the simulator that requires the microphone though, so that connection just stays unplugged.
