Which statement is true regarding ground power and PCA supply on incoming aircraft?

The statement that ground power and PCA (Pre-Conditioned Air) supply is provided for every aircraft except the B787 is accurate based on operational practices. Ground power is an essential service that allows aircraft to operate electrical systems while on the ground without needing auxiliary power units. PCA provides climate-controlled air to the cabin and cockpit to maintain a comfortable environment for passengers and crew when the engines are not running.

Most aircraft at the airport typically receive both ground power and PCA to ensure efficient operation after arrival and before departure, helping to minimize fuel consumption and reduce emissions. However, the Boeing 787 has specific requirements or a different system configuration that may limit or change how it connects to ground power and PCA systems, which is why the stipulation about the B787 is specifically noted. This distinction highlights the differences in various aircraft systems and their ground handling needs.

Understanding these operational procedures is crucial for ramp personnel as it ensures that each aircraft is handled correctly and efficiently according to its specific requirements, facilitating safe and timely turnarounds.
