Air Conditioning and Pressurization is covered by which ATA chapter?

• A. ATA 24 Electrical Power
• B. ATA 22 Auto Flight
• C. ATA 21 Air Conditioning and Pressurization
• D. ATA 11 Placards and Markings

Answer: (C)

ATA chapters are a standardized index for aircraft maintenance, with each chapter grouping information by a specific system. Air Conditioning and Pressurization is designated to the chapter that covers environmental control, including cabin air and pressure regulation. That makes the option describing Air Conditioning and Pressurization the correct match. The other options correspond to different systems: Electrical Power deals with power generation and distribution, Auto Flight with automatic flight guidance, and Placards and Markings with warning labels and cockpit markings.
