Cobham is the leader in innovative solutions combining Audio and Radio Management in a single control display unit

Cobham offers several Audio and Radio Management Panels for use on civil and military aerospace subsonic platforms.



Radio & Audio Integrated Management System (RAIMS):

  • The RAIMS has been designed for Long Range (LR) and Wide Body (WB) aircraft. It consists of two to three Radio Management Panels (RMP) associated with two Audio Management Units (AMU4032) integrating SELCAL and cockpit amplifier functions. This advanced controller provides the following main functionalities: radio communication management, audio management, Satcom dialing, and radio navigation frequency management (in back-up) in a single point-of-control for crew members.
  • It is interfaced with all CNS radios, FMS, Aircraft Environment Surveillance Unit (AESU), Avionics Communication Router (ACR) and Satellite Data Unit (SDU).


Audio & Radio Control Display Unit (ARCDU):

  • Cobham's ARCDU is a customizable controller display unit, perfectly suited for line-fit and retrofit programs for helicopters, trainers and mission aircraft. It can be associated with two different AMUs: with the AMU4242 for trainers and medium and heavy mission aircraft; and with the AMU50 for helicopter and light mission aircraft.
  • The typical architecture is comprised of two ARCDU, one AMU, and optional ACPs as the ACP51 or ACP3000 depending of the AMU type.
  • The ARCDU is an intuitive device allowing quick access to navigation, communication, transponder / identification radio units.  It benefits from dynamic, configurable software and modular design to match any customer requirements.
  • It is compatible with most radios using ARINC429, RS422, RS485 and MIL-STD-1553. Specific interfaces may be made available on request.
