What frequently produces smoke in the cockpit?

• A. Overheated electronic components
• B. Electrical wiring shorts
• C. Ruptured coolant lines resulting from either engine overheating or leaking fluid
• D. Cabin lighting

Answer: (C)

Smoky conditions in the cockpit are most often linked to the cooling or fluid systems coming into contact with hot engine areas. When coolant lines rupture or leak, the hot coolant spills onto hot engine components or exhaust areas. The fluid rapidly vaporizes and smokes, creating visible smoke and a distinctive odor. Engine overheating makes these lines more likely to fail, so a rupture from overheating or fluid leakage is a common source of cockpit smoke. While overheating electrical components or wiring faults can also produce smoke, they’re less frequently encountered as the primary cause in typical cockpit smoke scenarios. Cabin lighting by itself would not generate smoke.
