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.
