Final answer:
The correct location for the APU air intake and exhaust is both on the tail of the aircraft, making option (b) the correct answer.
Step-by-step explanation:
The Auxiliary Power Unit (APU) is a critical component found on many aircraft. Its functions include providing electrical power and pneumatic pressure for various systems, especially when the main engines are not running. Regarding the location of the APU's air intake and exhaust, the most typical configuration on modern airliners is:
- Air intake: Located near the tail of the aircraft.
- APU exhaust: Also located at or near the tail, but specifically designed to direct the exhaust gases away from the aircraft.
To directly answer the question, the correct choice is (b) Air intake: On the tail; Exhaust: Near the engine, although the term 'near the engine' should be understood as 'the APU engine which is located near the tail', not the aircraft's main propulsion engines.
