Ground Power and Pre-Conditioned Air (PCA) is supplied on every arriving aircraft, except for which model?

The Boeing 787 model is notably different from other aircraft in terms of its ground power and Pre-Conditioned Air (PCA) requirements. This aircraft features advanced systems that allow it to operate efficiently while using less power when on the ground. Notably, the 787 can utilize its onboard batteries for power needs and is designed to require less external power source compared to other models like the B777, A350, or B737. This self-sufficiency is a key aspect of its engineering, which reduces dependency on ground support systems, making it unique in this regard. Consequently, this model is not supplied with ground power and PCA in the same way as the others, which typically rely on such external conditions for cabin comfort and electrical power.
