What is the acceptable oil pressure range during aerobatic maneuvers or spins?

The acceptable oil pressure range during aerobatic maneuvers or spins is integral to ensuring the engine operates effectively under conditions that may create variable loads and orientations. The correct range of 40 to 130 psi is specified because it allows for sufficient lubrication in various flight attitudes, particularly those encountered during aerobatics. This range ensures that the oil system can maintain adequate pressure to prevent engine damage while performing potentially high-stress maneuvers.

Operating within this range reduces the risk of oil starvation or pressure drop that can occur in more extreme maneuvering, thereby maintaining engine health and performance. It is crucial for pilots to be aware of these parameters to ensure safe operation during aerobatics or spins, as oil pressure is a key indicator of engine function.

Understanding this range helps pilots preemptively manage engine performance and make informed decisions should the oil pressure deviate from expected levels during flight.
