What must be monitored after exceeding 127 °C oil temperature?

• A. Fuel levels
• B. Oil pressure
• C. Engine RPM
• D. N1 levels

Answer: (D)

The requirement to monitor N1 levels after oil temperature exceeds 127 °C is essential to ensure the engine operates safely and efficiently. Elevated oil temperatures can indicate that the oil is losing its viscosity and lubricating properties, which could lead to increased wear or damage to engine components. Monitoring N1, which is the speed of the engine's gas generator, helps ensure that the engine remains within safe operational limits, preventing potential engine failure.

By keeping a close watch on N1 levels, pilots can be alerted to any abnormal behavior that may arise from high oil temperatures, allowing for timely corrective actions to maintain performance and safety. This focus on N1 is interconnected with the overall health of the powerplant, reflecting engine status and overall operational integrity.
