What is the maximum temperature for the oil temperature gauge?

The maximum temperature for the oil temperature gauge is specified at 99°C. This limit is established to ensure proper engine performance and longevity by preventing overheating, which can lead to engine wear and failure. Oil plays a critical role in lubricating engine components, and maintaining it within the specified temperature range is essential for optimal operation. Exceeding the maximum temperature can degrade the oil’s effectiveness, thus compromising lubrication and increasing the risk of engine damage.

Choosing 99°C as the maximum oil temperature aligns with manufacturer guidelines intended to promote safe and efficient engine operation. In contrast, other temperature options either fall below this critical threshold or present values that would indicate a dangerous operating condition for the King Air 350, thereby making them not applicable for safe flight operation.
