Radio Management panel, one for each pilot and a third for the observer
AMU = Audio Mangement
Unit: arranging audio
for all equipment on board
ACP = Audio Control Panel, one for each pilot and a third for the
the AMU the HF system is selected 'on' and the RX volume is being set.
The AMU has a
switch to PTT the (HF) system. This switch is doing the same as
the PTT switch on the
microphone. Because of my position in the cockpit under such
circumstances (on the 'fourth
seat, behind the pilot on the right hand side) I prefer to use the PTT
on the hand microphone.
