What is the maximum allowable oil temperature during takeoff for the King Air 350?

The maximum allowable oil temperature during takeoff for the King Air 350 is 110°C. This limit is crucial for ensuring the engine operates within safe thermal parameters, promoting optimal performance and preventing damage due to overheating. Oil temperature directly affects the lubrication properties of the oil; higher temperatures can degrade oil quality and reduce its effectiveness in protecting engine components.

The specified maximum of 110°C is set by the manufacturer based on extensive testing and operational guidelines to maintain engine health and efficiency. Exceeding this temperature could risk engine failure or other mechanical issues, thus strict adherence to this limit is vital during critical phases of flight like takeoff, where engine performance is paramount.

Other temperature settings, such as 90°C, 100°C, or 120°C, do not align with the manufacturer's recommended limits for takeoff conditions in the King Air 350. The selection of 110°C is established as a safe threshold in correspondence with engine design and testing data to ensure pilots operate within safe parameters.
