What should be the oil pressure range when performing aerobatics or spins?

When performing aerobatics or spins in a T-6, the required oil pressure range must be carefully monitored to ensure proper engine lubrication and performance under varying flight conditions. The correct range of 40 to 130 PSI is crucial because it indicates that the oil system is functioning effectively, providing adequate lubrication to all critical engine components even during the high G-forces and rapid changes in orientation that occur during these maneuvers.

An oil pressure within this range helps prevent engine damage and ensures that the engine operates smoothly, allowing for a safer aerobatic experience. If the oil pressure falls below 40 PSI, it may indicate inadequate oil flow, which could lead to engine failure. Conversely, if the pressure exceeds 130 PSI, it may signify an issue with the oil system, such as an obstruction or overpressure conditions, which could also compromise engine safety. Hence, maintaining oil pressure within the established limits is essential for the safe execution of aerobatic maneuvers.
