What is the minimum oil pressure during aerobatics/spins?

In aerobatic flying and spins, maintaining adequate oil pressure is crucial for the engine's lubrication and overall functionality. The minimum oil pressure specified for aerobatics is typically set at 40 PSI. This value ensures that the oil system can effectively distribute oil to critical engine components, even during the high-g maneuvers associated with aerobatics.

If the oil pressure drops below this threshold, it may indicate insufficient lubrication, which could lead to engine failure or damage under the stress of aerobatic maneuvers. This is particularly important during spins, where engines are often subjected to extreme conditions. Therefore, a minimum oil pressure of 40 PSI provides a safety margin to ensure the engine remains well-lubricated and operates reliably during these demanding flight conditions.
