Prima-MV airborne VHF radio (10 W)
Prima-MV radio set is intended for providing telephone radio communication on the fixed frequencies of VHF range between aircraft and ground control unit.
Рrima-MV radio simultaneously provides functions of 4 devices:
- transceiver;
- intercommunication system (ICS) (up to 3 users);
- voice warning system (VWS) (up to 32 messages);
- marker receiver.
The radio set provides:
- preliminary VHF radio communication channels programming;
- monitoring of the emergency channel in VHF range; audio and light indication of the signal on the emergency channel frequency (121.5 MHz);
- voice messages generation according to the signals from information and control aircraft transducers;
- reception of the airborne marker beacons radio signals from additional antenna input; audio and light indication of the radio signals;
- voice information transmission to cockpit voice recorder;
- voice information transmission to external loudspeaker;
- controlling all the functions from its own or external control panel (CP).
The radio set provides the following telephone communication:
- external two-way simplex radio communication for one pilot (with listening to the conversations by other pilot);
- external two-way simplex radio communication for one pilot via additional radio set;
- internal radio communication in ICS mode (conference -call) between two pilots and one passenger with volume control;
- listening by each pilot:
- navigation systems signals with volume control;
- the signals from the special signals transducers with volume control;
- voice messages, generated in the radio set;
- marker radio beacons from embedded marker receiver.
