What is the GPU amperage required for starting the APU?

The answer of 1,000 amps is correct because the Falcon 2000LXS requires a substantial amount of electrical current to initiate the Auxiliary Power Unit (APU). The APU needs this high level of amperage to overcome inertia and engage its starter motor effectively.

Starting the APU is a critical phase during pre-flight operations, as it provides essential electrical power and air conditioning before the main engines are started. The specified amperage is part of the aircraft's operational requirements, ensuring sufficient power to start the APU without any electrical issues or performance setbacks.

Understanding this requirement is vital for flight crews and maintenance personnel, as using an incorrectly rated Ground Power Unit (GPU) could lead to difficulties in starting the APU, potentially resulting in operational delays or safety concerns. The other amperage options do not meet the aircraft’s operational demands for APU start-up and could either fail to start the APU or provide insufficient power, highlighting the importance of knowing the correct specification.
