Pre-Conditioned Air Units (PCA)

Pre-Conditioned Air Units (PCA) are specialized systems used at airports to supply aircraft with cooled, heated, or filtered air while they are on the ground. They help maintain the aircraft's interior climate and ensure comfort for passengers and crew before takeoff. PCA units attach to the aircraft through a plug or hose, providing a controlled environment without needing the aircraft's engines or auxiliary power units to run. This process reduces fuel consumption, emissions, and engine wear, supporting efficient and environmentally friendly aircraft operation during ground handling.
