Correct Answer
C. Start the APU if the APU MASTER SW was previously selected on.Explanation
When the APU START push button is selected, it will start the APU if the APU MASTER SW (switch) was previously selected on. This means that the APU can only be started if the APU MASTER switch is in the on position. The APU START push button does not directly connect the APU generator to the aircraft electrical system or open the air intake flap and supply fuel pressure. It is solely responsible for starting the APU if the APU MASTER switch is already on.Rate this question:
