Aircraft Air Conditioning, Heating, and Pressurizing Equipment

FSC 1660: Aircraft Air Conditioning, Heating, and Pressurizing Equipment

Federal Supply Class (FSC) 1660 covers environmental control system (ECS) components including air conditioning, heating, and pressurization equipment installed on military aircraft. Parts are sourced to MIL-SPEC and OEM standards.

These systems maintain cockpit and cabin temperature and pressure and provide cooling air for avionics. Habitability and equipment cooling are essential to crew effectiveness and mission system reliability.

Common items include air cycle machines, heat exchangers, pressurization controllers, valves, ducting, and cabin heaters. Components are built from aluminum, stainless steel, and high-temperature alloys to handle bleed air and thermal loads.
