What is the maximum transient oil pressure during aero/spins?

The correct answer is 130 psi as the maximum transient oil pressure during aero/spins is established based on operational limits specified in aircraft technical data. In aviation, particularly in aircraft systems, there are specific thresholds for various parameters including oil pressure to ensure safe and effective operation of the engine and related systems. When an aircraft undergoes maneuvers that induce transient conditions, such as aerobatics or spins, the oil pressure may temporarily exceed normal operating values, but within defined limits.

130 psi is recognized as the maximum pressure that can occur during such transient conditions without compromising engine operation or causing damage. Understanding these limits is crucial for pilots and maintenance personnel, as it helps to inform them of the operational envelope within which the aircraft can safely operate during potentially stressing maneuvers. This knowledge is vital for ensuring the safety and performance of the aircraft under all flight conditions.
