Does the sim use an ADF with a fixed compass card or is it a rotatable compass card? Or is it just an RMI? I haven't used it in a long time, and I'm not anywhere near FS right now so I can't check.
Also, with the RMI, you can tune it to either NDBs or VORs, can't you? Or is it just NDBs? I've never actually used one, but it seems like if you could tune it to a VOR and have a CDI for the same VOR, it would be too easy almost. But now I'm just talking about a HSI, aren't I? I think it's too late and I'm just confusing myself now...
I think I just re-invented the wheel and sliced bread.
Some planes in the sim use the RMI. I know the KingAir is one of them for sure; I forgot the other. It also has a fixed compass card. Some others, like the Cessna, have ADFs with a rotatable compass card and no RMI.
I believe RMIs can be tuned to both NDBs and VORs, as long as the VOR being used is in Nav-2. There is an earlier post in this thread that clears that up, refer to that in case I'm wrong.
