IGLM.301433.003-46 / PDU-46

Radio station control through PDU-46

The PDU-46 panel allows the crew to control the radio station without direct access to the main transceiver unit. Through the panel, the crew can select operating channels, set communication modes and manage the connected VHF radio equipment from the cockpit. This arrangement allows the main radio transceiver to remain installed in the radio compartment while all required operational controls stay available to the crew.

IGLM.301433.003-46 in the Orlan-85ST system

IGLM.301433.003-46 operates exclusively as part of the Orlan-85ST aircraft radio communication system. The panel is not a standalone communication device and does not transmit, receive or amplify radio signals by itself. Its role is limited to control and selection functions within the complete radio station set. Correct operation depends on the Orlan-85ST transceiver, power supply unit, wiring, connectors and related system components.

PDU-46 as a cockpit interface

The PDU-46 serves as the human–machine interface between the flight crew and the radio station transceiver installed in the aircraft radio equipment compartment. It provides cockpit access to channel and mode selection during flight and ground operation. The panel should be checked together with its mounting, connectors, control elements, indication, wiring and communication with the main radio unit.

Aircraft application of IGLM.301433.003-46 / PDU-46

The IGLM.301433.003-46 / PDU-46 control panel is intended for civil aviation aircraft and helicopters equipped with the Orlan-85ST VHF radio station. Since aircraft communication installations may differ by aircraft type, modification and installed radio package, applicability should be confirmed through the aircraft equipment list, wiring documentation and Orlan-85ST technical documentation before supply or replacement.

Identification and ordering of IGLM.301433.003-46 / PDU-46

The unit may be referenced as IGLM.301433.003-46, PDU-46, PDU-46 or remote control panel for the Orlan-85ST radio station. In supply lists, it may also appear 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.
