Each radio operates independently and will receive whatever is onchannel. However, usually the radios (and other things that make noises) are wired through the so-called audio panel that decides which combination of sounds is sent to the speaker and/or the headset and/or any other place that sound can be heard. In a C172, all the headsets are usually wired together, so there is only one switchable entry for headsets. Many panels have a "radio 1/2" switch, that decides which radio gets the microphone. In this situation, instead of "COM1" and "COM2" inputs, you might have "SEL" and "UNSEL" "BOTH" buttons, or a combination of them. On a hypothetical C172, your sources are ...

This can increase panel complexity, although no effect on other operations. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
