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

• A. 5 minutes
• B. 10 minutes
• C. 15 minutes
• D. 20 minutes

Answer: (B)

The correct choice indicates that the oil temperature can be in the range of 99-110°C for a maximum of 10 minutes. This limitation is crucial for the safe operation of the King Air 350, as prolonged exposure to elevated oil temperatures can potentially cause damage to the engine or lead to less efficient operating conditions.

Operating within this temperature range for up to 10 minutes allows for temporary deviations from standard parameters, which could be necessary during certain operational scenarios, such as during takeoff or climb phases, without compromising the engine's integrity. Exceeding this duration may lead to overheating and subsequent engine wear or failure, making it vital for pilots to monitor oil temperature closely and adhere to these limitations to ensure safety and reliability in flight operations.
