AVCATT (Aviation Combined Arms Tactical Trainer) is a mobile aviation training simulator developed by L-3 Communications, Link Simulation & Training for the United States Army. Mission: The AVCATT is an Army aviation training system for Active, Reserve and Army National Guard components. AVCATT supports unit collective and combined arms training for the AH-64, UH-60, CH-47 and OH-58 aircraft. Other AVCATT modules, such as the Non-Rated Crewmember Manned Module ((NCM3), a sub-system of AVCATT), can be linked to this basic configuration, when and where needed, to support specific unit training requirements. The NCM3 supports the training of non-rated crew members in crew coordination, flight, aerial gunnery, hoist and slingload-related tasks.
