Communications menu only working on ground

Since the update from 2.5 to 2.5.1, the communication menu only seems to work on the ground if you're using "Communication menu" button (\ by default); no matter if Easy Communications is enabled or disabled. Once airborne, it won't work anymore. That was definitively not the case in 2.5.

The menu appears on ground and airborne if you're using "RADIO - Trigger radio" (Ralt + \).

I'm just wondering if this is by design or if this is a bug (it's the same with the UH-1H btw)?

I simply bound my button to Ralt + \ now. However, I can't quite see why the "Communication menu" shall only work while on the ground?

I disagree, \ was working fine airborne in DCS 2.5 with Easy Communications enabled. Anyway, I changed it to Ralt+\ now for 2.5.1...

A long time ago I had this same problem in the testing build, but had forgotten that there are 2 separate ways/keystrokes to access the coms menu.

I'm at work, so this may not work because they may have removed this function, but while you're in the air, look across at your co-pilot, lean forwards and (if the detection box still exists) you should be able to click the push to talk button on his stick.

If that brings up the coms menu, you're using the wrong keystroke.
