pre-conditioned air units

Pre-conditioned air (PCA) units provide a steady supply of cooled or heated air to aircraft parked on the ground, maintaining a comfortable environment and preventing issues caused by extreme temperatures. These units connect to the aircraft’s system via specialized hoses, allowing crew or maintenance personnel to manage cabin temperature and air quality without deploying onboard environmental controls. PCA units improve passenger comfort, aid in aircraft maintenance, and conserve aircraft power, especially when engines are shut down. Overall, they ensure efficient climate control on the ground, supporting safety and operational efficiency during aircraft turnaround times.
