Sub-freezing PCA System Keeping coolground on the Ways to regulate the cabin air temperature APU restrictions and fuel savings At the gate, the cabin must be kept to an acceptable temperature for the passengers’ and maintenance personnel’s comfort. To ensure this, there are three possible ways. 1. The ‘bleed air’ from the aircraft powered by the APU compressor (high pressure), provides a high cooling capability. The bleed air is cooled by the air conditioning packs, mixed to the cabin air thanks to recirculation fans, and then supplied to the various compartments. This air is then mostly...

Gate Operator Terminal Cavotec E³ gates incorporates a Gate Operator Terminal (GOT) which is one of the key Sub-freezing PCA safety features able to communicate with the VDGS and Flight Management System which ensures accurate information of the aircraft type to be serviced at the gate or apron. The system includes a complete database of Airbus, Boeing and other representative aircraft with individual settings and limitations for safe ground operations in compliance with AHM997 and AHM974. 4.
