What is the engine oil pressure range for continuous operation?

• A. 70 to 90 psi
• B. 60 to 120 psi
• C. 80 to 110 psi
• D. 100 to 120 psi

Answer: (C)

The engine oil pressure range for continuous operation in the TH-73A is specified as 80 to 110 psi. This range is critical for ensuring proper lubrication and cooling of the engine components during operation. Maintaining oil pressure within this specified range helps to protect the engine against wear and failure, as adequate oil flow ensures that moving parts are lubricated, reducing friction and the risk of overheating. Operating outside of this range could lead to insufficient lubrication, which can increase the risk of engine damage due to component wear or even engine failure. Therefore, it's essential for pilots and maintenance personnel to monitor these pressures closely during flight operations to ensure the engine operates within safe parameters.
