Final answer:
The APU control panel and the APU FAULT indication panel are located on the flight deck of an aircraft. These panels allow the flight crew to manage the Auxiliary Power Unit for operations when the main engines are not running.
Step-by-step explanation:
The APU control panel and the APU FAULT indication panel are key components in an aircraft used for managing the Auxiliary Power Unit (APU). The correct answer to the question is that these panels are located on the flight deck. The APU provides power to the aircraft when the main engines are not running, such as during ground operations or in-flight emergencies. Flight crew members use the control panel to start and monitor the APU, while the FAULT indication panel alerts them to any potential issues or malfunctions with the APU system.
