Which ATA chapter covers Airborne Auxiliary Power?

Which ATA chapter covers Airborne Auxiliary Power?

• A. Fuselage
• B. Airborne Auxiliary Power
• C. Nacelles/Pylons
• D. Information Systems

Answer: (B)

In ATA documentation, chapters are organized by the system area they cover, so the chapter name itself signals the scope of maintenance data. Airborne Auxiliary Power is the chapter that specifically addresses devices and systems that supply power to the aircraft when primary sources aren’t providing it, such as the APU, starter-generators, and related power distribution and starting systems. This makes it the best fit for the topic. The other options refer to structural or non-power-system areas—fuselage and nacelles/pylons are about physical airframe parts, and information systems covers avionics and data flow—not power generation or distribution.
