A communications interface adapter facilitates both wired and wireless communications between crew members of a vehicle having a wired intercom and has an intercom communications circuit having an input/output port for providing electrical communication between the interface adapter and the wired intercom and also has a fixed radio transceiver. The fixed radio transceiver comprises a receive circuit for receiving radio communications and for communicating the received radio communications via the intercom communications circuit to the wired intercom of the vehicle and a transmit circuit for transmitting communications received via the intercom communication circuit from the wired intercom of the vehicle. A crew member is provided wired communications with the wired intercom when the crew member's headset is in electrical communication with the wired intercom and is provided wireless communications with the wired intercom via the fixed radio transceiver and the crew member's portable radio transceiver when the crew member's headset is not in electrical communication with the wired intercom.
