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.

A personal communications unit facilitates both wired and wireless communications with a wired intercom. The personal communications unit has a headset, an intercom connection cable placeable in electrical communication with the wired headset and also placeable in electrical communication with the wired intercom, a radio transceiver which is placeable in electrical communication with the headset, and a switching circuit which is configured to place the intercom connection cable in electrical communication with the headset when the intercom connection cable is in electrical communication with the wired intercom and which is configured to place the radio transceiver in electrical communication with the headset when the intercom connection cable is not in electrical communication with the headset. Wired communications with the wire intercom are facilitated when the intercom connection cable is connected to the wired intercom and wireless communications with the wired intercom are facilitated when the intercom connection cable is disconnected from the wired intercom.
