What is the transmission oil temperature range for continuous operation?

• A. -10 to 110 C
• B. 0 to 115 C
• C. 10 to 120 C
• D. 0 to 100 C

Answer: (B)

The correct range for transmission oil temperature during continuous operation is from 0 to 115 degrees Celsius. This range is important for ensuring the efficient operation of the TH-73A's transmission system. Operating within this temperature spectrum helps maintain appropriate lubrication and cooling, which are essential for the transmission's performance and longevity.

Exceeding this temperature index could lead to increased wear and tear on transmission components, impairing their functionality. Additionally, keeping the temperature within this specified range helps prevent overheating, which could result in catastrophic failure of the transmission system.

Understanding this temperature range is crucial for pilots and crew to monitor during various phases of flight, ensuring optimal operational conditions and maintaining the safety and performance of the aircraft.
