During continuous operation, what is the acceptable transmission oil pressure range?

• A. 30 to 55 psi
• B. 30 to 60 psi
• C. 30 to 70 psi
• D. 30 to 80 psi

Answer: (A)

The acceptable transmission oil pressure range during continuous operation is 30 to 55 psi. This range is important because it ensures the proper lubrication and functioning of the transmission system. Maintaining the oil pressure within this specified range helps prevent excessive wear on components, overheating, and potential system failures. Operating outside of this pressure range could lead to inadequate lubrication, resulting in damage to the transmission system over time. It is essential for pilots and maintenance personnel to monitor these parameters closely to ensure safe and efficient aircraft operation.
