Which chapter covers water ballast systems?

• A. Oxygen
• B. Water / Waste
• C. Water Ballast
• D. Cabin Systems

Answer: (C)

Water ballast is a distinct system in aircraft maintenance, specifically used to adjust weight and balance by filling or draining ballast tanks. In ATA documentation, such specialized systems have their own dedicated chapter so technicians can access all related components, procedures, and troubleshooting in one place. That makes the Water Ballast chapter the best fit because it directly covers ballast tanks, pumps, valves, sensors, and the proper filling and draining procedures. The other topics address different systems: Oxygen deals with breathing air and oxygen equipment; Water / Waste covers potable water and lavatories/waste management; Cabin Systems encompasses cabin-related services and environmental control. Since ballast is a separate, specialized system, it belongs in its own Water Ballast chapter.
