The Aircraft Wireless Intercom System (AWIS), a joint development with the U.S. Navy, provides increased safety and mission performance such as medical evacuation of helicopter crew members and medical personnel during hoist rescue, and whenever flight medical crew members are conducting dismounted patient recovery missions in proximity to the aircraft. AWIS supplements the current aircraft corded intercom system for both flight and ground operations for the Army’s CH-47 and HH/UH-60 aircraft, and the Navy’s CH-46, SH-60, and CH/HH-53 aircraft. The system consists of one aircraft interface unit, up to six mobile equipment units, and one support station including battery charger.

AWIS provides:

Hands-free communication between hoist operators and rescue personnel on the hoist

Full duplex voice-activated mode, hands-free mode, and a push-to-talk mode


Fifty independent channels (aircraft networks) with up to six crew members on each aircraft network

Simultaneous omnidirectional communications among all users in the aircraft network within 200 feet of the center of the aircraft.
