Which chapter covers pneumatic systems such as air distribution and bleed air?

• A. Cabin Systems
• B. Pneumatic
• C. Vacuum / Pressure
• D. Oxygen

Answer: (B)

The concept here is recognizing which ATA chapter deals with systems that use compressed air. Pneumatic systems rely on bleed air generated by engines or the APU, which is distributed through ducts to provide cabin pressurization, air conditioning, and other conditioned air functions. That entire network and its components fall under the Pneumatic chapter. Cabin Systems covers items specifically located in the cabin but not the air-pressurization and bleed-air distribution network itself. Vacuum / Pressure pertains to vacuum systems and pressure-related instruments, not the bleed-air distribution system. Oxygen relates to oxygen generation and supply, not the regular air distribution and pressurization system. So the best answer is the Pneumatic chapter.
