How long can the oil temperature be in the range of 99-110°C?

The correct answer indicates that the oil temperature can remain in the range of 99-110°C for a maximum of 10 minutes. This limitation is important for the safe operation of the King Air 350, as exceeding recommended temperatures for prolonged periods can lead to engine damage or reduced performance.

Oil temperature is crucial for ensuring proper lubrication and functionality of the engine. Operating at elevated temperatures can compromise the oil's integrity, leading to increased wear and potential engine failure. Therefore, the limitation imposed is a safeguard to ensure that pilots operate within safe temperatures that allow for effective cooling and lubrication without incurring risk.

This specific limitation of 10 minutes allows for some flexibility during operations, such as takeoff or climb, where temporary oil temperature spikes can occur due to higher engine loads. Awareness and adherence to this guideline help to maintain the longevity and reliability of the aircraft’s engine systems.
