Pre-conditioned air (PCA) systems provide the aircraft cabin with conditioned air at the park position. As a result, the parked aircraft no longer needs to run their auxiliary turbine for air conditioning. The PCA systems are significantly quieter during operation and reduce kerosene consumption and related CO2 emissions.
What is PCA?
Pre-conditioned air systems provide an external supply of conditioned air to cool, ventilate and heat the cabins of parked aircraft. Munich Airport has installed 64 of these systems at all pierside aircraft positions of both terminals and the satellite facility.
