What is the oil pressure range for aerobatics/spins?

The oil pressure range for aerobatics and spins is correctly identified as 40 to 130 PSI. This range is important because during aerobatic maneuvers, the aircraft experiences various forces and conditions that can impact engine performance and oil circulation.

A minimum oil pressure of 40 PSI ensures that the oil system is adequately lubricating the engine under high-load conditions, which can occur during aggressive flying. The upper limit of 130 PSI accommodates the increased pressure that may result from the dynamic maneuvering of the aircraft, ensuring that the oil system remains functional and effective in providing lubrication without risking damage due to excessive pressure.

Selecting this range ensures that the engine remains within safe operational limits, thereby preventing potential mechanical failures that could arise from inadequate oil circulation or excessive pressure. This consideration is critical for maintaining engine health and performance during aerobatic flight where oil pressure levels can fluctuate.
