Carburettor Heat
Carburettor heat is a system that introduces heated air into the engine's carburettor to prevent or clear ice formation, such as throttle ice or fuel evaporation ice. Because the heated air is less dense, applying carburettor heat during take-off or in flight reduces the engine's power output (RPM) and decreases climb performance.
Key Points
- •Carburettor heat is used for anti-icing and de-icing of the carburettor.
- •It reduces power output (RPM) due to decreased intake air density.
- •Applying carburettor heat decreases climb performance.
- •Its operation is routinely checked prior to take-off.
Exam Relevance
Students must know the operational effects of applying carburettor heat, particularly how it decreases RPM and climb performance.
