What is the continuous amp requirement for external ground power?

The continuous amp requirement for external ground power for the T-6A is 300 amps. This specification is crucial as it ensures that the external power unit can effectively supply sufficient electrical energy to meet the demands of the aircraft systems during ground operations, especially when the engines are not running. The 300 amps provide the necessary support for both starting the aircraft and powering onboard systems without overloading the external power source. Understanding this requirement helps in ensuring that proper ground power units are used, which is essential for safe and efficient ground operations.
