Which chapter covers pneumatic systems?

Which chapter covers pneumatic systems?

• A. Oxygen
• B. Water Ballast
• C. Electrical - Electronic Panels and Multipurpose Components
• D. Pneumatic

Answer: (D)

In ATA-style manuals, information is grouped by system, with each system having its own dedicated chapter. Pneumatic systems use compressed air for functions like actuation and environmental control, so all components, diagrams, troubleshooting, and maintenance procedures for those air-powered parts belong together in the Pneumatic chapter. That makes it the correct place to look for information on compressors, valves, regulators, actuators, and related piping. Oxygen has its own chapter because it covers the compressed oxygen supply, masks, regulators, and safety procedures specific to that system. Water ballast isn’t a standard aircraft system for most airliners and would be covered elsewhere if applicable. Electrical aspects and electronic panels sit in their own chapter focused on power distribution and avionics.
