What are the CHT gauge readings used for in the Beechcraft Travel Air BE‑95?

The CHT (Cylinder Head Temperature) gauge readings in the Beechcraft Travel Air BE-95 are primarily used to monitor the engine temperatures, specifically the temperature of the cylinder heads. This information is critical for assessing engine performance and ensuring that the engine operates within safe temperature limits. High cylinder head temperatures can indicate potential issues such as lean mixtures or overheating, which could lead to engine failure if not addressed. Monitoring these readings allows pilots to detect problems early enough to take corrective action, thus ensuring the safety and reliability of the flight.

In aircraft, managing engine temperatures is vital, especially during climb, cruise, and descent phases, as each has different demands on the engine. The CHT readings help pilots ensure that they are operating the engine efficiently and within its designed operational boundaries.
