IGLM.301433.003-32 / PDU-32

Radio station control through PDU-32

The PDU-32 panel acts as the crew interface between the cockpit and the radio transceiver installed in the aircraft radio equipment compartment. Through the panel, the crew can select operating channels, set radio communication modes and control the connected VHF radio equipment without direct physical access to the main transceiver unit. This arrangement allows the transceiver to remain installed in the radio compartment while radio control remains available from the cockpit.

IGLM.301433.003-32 in the Orlan-85ST system

IGLM.301433.003-32 is intended for use with the Orlan-85ST aircraft radio communication system. The panel works together with the Orlan-85ST VHF transceiver and related radio station components. Its function is limited to control and selection tasks; it does not transmit, receive or amplify radio signals by itself. Correct operation depends on the connected radio station, wiring, power supply, connectors and the aircraft communication control installation.

Aircraft application of PDU-32

The PDU-32 remote control panel is used on civil aviation aircraft and helicopters equipped with the Orlan-85ST radio station set. The unit supports crew control of VHF radio communication during flight and ground operation. Since radio installations may differ by aircraft type, modification and installed communication package, applicability should be confirmed through the aircraft equipment list, wiring documentation and Orlan-85ST technical documentation before supply or replacement.

Installation of IGLM.301433.003-32 in the cockpit

The IGLM.301433.003-32 / PDU-32 panel is installed in the aircraft cockpit, normally in the radio control area or communication equipment panel depending on aircraft layout. It is designed for continuous operation under aviation conditions, including vibration, temperature variation and electrical loads typical for onboard equipment. During inspection or replacement, the panel should be checked together with its mounting, connectors, control elements, indication, wiring and communication with the main transceiver.

Identification and ordering of IGLM.301433.003-32 / PDU-32

The unit may be referenced as IGLM.301433.003-32, PDU-32, PDU-32 or remote control panel for the Orlan-85ST radio station. It may also appear in supply lists as an onboard remote control panel or radio station control panel. For correct supply, it is useful to specify the aircraft type, installed Orlan-85ST system, required condition, documentation requirements and whether the request concerns the control panel only or the complete radio station set.
