What is the maximum oil temperature allowable in flight?

The maximum allowable oil temperature in flight for the T-6 is indeed 110 degrees Celsius. This limit is set to ensure the effective operation of the engine and the overall health of the aircraft systems. Maintaining oil temperature within this range is crucial because oil serves multiple purposes, such as lubricating engine components, cooling the engine, and providing a seal in certain parts of the engine. If the oil temperature exceeds 110 degrees Celsius, it can lead to diminished oil viscosity, reduced lubrication efficiency, and potential engine damage.

When operating an aircraft, adhering to the specified operational limits, including oil temperature, is vital for safety and performance. Operating above this temperature could lead to overheating issues and may trigger system warnings or failure. Understanding and adhering to this limit helps ensure both the aircraft's longevity and the pilot's safety in flight operations.
