Smoke detection in the cockpit will illuminate which indicator?

• A. Warning Horn
• B. Caution Lights
• C. Engine Fire Light
• D. Master Caution

Answer: (B)

When smoke is detected in the cockpit, the warning system treats it as an abnormal condition that requires attention but isn’t necessarily an immediate engine fire. The appropriate alert is the caution lights, which are designed to draw attention to non-emergency but important issues that need investigation. The warning horn is typically tied to a more urgent master warning, and the engine fire light is specific to an engine fire condition. So the cockpit will illuminate the caution lights to prompt you to identify and address the source of the smoke. If the situation escalates to a fire, you’d see a stronger alert pattern and related indicators.
