Cylinder Head Temperature (CHT)
Cylinder Head Temperature (CHT) is an engine instrument that measures the temperature of the engine's cylinder heads, providing a direct indication of engine cooling efficiency. Pilots must monitor CHT to ensure the engine remains within its structural thermal limits, particularly during prolonged climbs.
Key Points
- •CHT monitors the effectiveness of the engine cooling system.
- •Excessively high CHT can lead to pre-ignition or detonation.
- •CHT is controlled through adjustments to airspeed, cowl flaps, and mixture settings.
Exam Relevance
Tested on the causes and effects of high CHT, including the potential for detonation, and the pilot actions required to cool the engine.
