What is the maximum permissible load on the APU generator?

The maximum permissible load on the APU generator is 40 kVA. This limitation is established to ensure that the Auxiliary Power Unit can operate efficiently and safely without being overtaxed. Exceeding this limit could lead to overheating and possible failure of the APU, which could compromise both electrical power needs and operational safety during ground operations. It is essential for pilots and maintenance personnel to be aware of this limitation, as exceeding it can negatively affect the aircraft's systems powered by the APU. Additionally, adhering to this limit helps maintain the longevity and reliability of the APU, ensuring it remains a dependable source of power during ground operations.
