Which ATA chapter covers Bleed Air?

Which ATA chapter covers Bleed Air?

• A. Bleed Air
• B. Ignition
• C. Powerplant
• D. Engine Controls

Answer: (A)

Bleed air is part of the aircraft’s pneumatic system. In ATA documentation, the topic of bleed air is grouped under a dedicated Pneumatic/Bleed Air chapter because it covers how compressed air bled from the engines is used to operate systems like environmental control, anti-ice, and cabin pressurization. The other options point to different engine-related areas—ignition handles starting and spark, powerplant covers the engine as a whole, and engine controls deal with control logic—so they don’t address the bleed air system. Since the subject matter specifically belongs to the bleed air/pneumatic chapter, that choice is the best fit.
