Bleed air leak can indicate a fire hazard; which warning light is associated with this condition?

• A. Limit light
• B. Landing gear caution light
• C. Heater O/Heat
• D. Hydraulic pressure warning light

Answer: (C)

Bleed air is the hot, high-pressure air taken from the engine to feed the heater and other systems. A leak in that line can allow hot air to escape or ignite nearby components, creating a fire hazard. The warning light that signals problems in the heater/bleed air system is the Heater O/Heat indicator. When this light illuminates, it alerts you to an abnormal heater condition—often related to a bleed air leak or overheating—so you know to shut the heater down and isolate the bleed air to reduce fire risk. The other lights correspond to different systems (limits, landing gear, hydraulics) and do not indicate bleed air/heater problems.
