Prior to turning on the APU Generator what should the pilot do?

• A. Perform a full engine start sequence
• B. Set flaps to takeoff
• C. Ensure the stabilator and TACAN is clear of personnel
• D. Configure landing gear

Answer: (C)

Before turning on the APU generator, make sure the stabilator and TACAN area is clear of personnel. The APU start can cause hydraulic actuation and small movements of the tail surfaces; having people in that tail region could result in injury from unexpected stabilator movement or interference with the TACAN antenna. This safety step protects both crew and equipment during APU initiation. The other actions aren’t required for starting the APU. A full engine start sequence is a separate procedure, flap setting isn’t needed for APU operation, and landing gear configuration isn’t a prerequisite for engaging the APU.
