What is the acceptable oil temperature range for the TH-73A during operation?

• A. -10 to 110 C
• B. -5 to 115 C
• C. 0 to 115 C
• D. 5 to 120 C

Answer: (C)

The acceptable oil temperature range for the TH-73A during operation is from 0 to 115 degrees Celsius. This range ensures that the oil remains within a temperature where it can effectively lubricate and cool the engine components without risking degradation in performance or causing potential engine damage. Operating outside of this specified range may lead to reduced oil viscosity, increased wear, and potential failure of critical engine systems. Thus, adherence to this temperature limit is crucial for maintaining the aircraft's operational integrity and longevity. Proper monitoring of oil temperature is essential for pilots to ensure safe and efficient flight operations.
