Pre Conditioned Air and Providing Comfortable Aircraft Cabin Conditions on the Ground

PCA (Pre Conditioned Air) systems are used to introduce fresh conditioned air into an aircraft cabin, while the aircraft is parked at a gate or maintenance site. Air is filtered, heated or cooled, and moisture is removed before delivery to the aircraft. Once the conditioned air enters the aircraft coupler, at the end of the PCA hose, it is distributed through the aircraft cabin’s duct system and into the cabin.
