Hi Vassilii, Which C172 are you commenting on? For the default 3d version I've turned the cockpit engine noise down to allow the ATIS to be more audiable as though headsets are worn - you can hear the difference when using the 'v' key to switch to outside view and back. I haven't done this for the 2d panel c172 though yet, but probably will if there are no objections. However, I don't know what the inside of a light aircraft cockpit should sound like, unlike yourself! > In real life, you can either put the radio on the loudspeaker > (overhead), or put on the headset and have the radio in it. > In the former case, I believe the volume is higher than this > produced by fgfs.

At the time I made the recording I was running FG on Windows only, and set the volume for that platform. On some Linux installations (David Megginson and others reported it) it was apparently virtually inaudiable. I'm not sure what the relative state of play on this is at the moment, since I haven't run FG on Windows for a while now.
