What is the oil pressure range during aerobatics/spins?

The correct answer is based on the specific parameters set for oil pressure during aerobatic maneuvers and spins in the T-6A aircraft. For the T-6A, during aerobatics and spins, the oil pressure is sustained within an appropriate range to ensure that the engine receives adequate lubrication while enduring the stresses of these dynamic flight conditions.

In this case, the oil pressure range of 40 to 130 PSI is designed to maintain effective engine performance and reliability despite variations in G-forces and other flight maneuvers that can impact oil circulation and pressure. Keeping the oil pressure in this range allows pilots to operate within safe limits while performing aerobatics, ensuring the engine remains properly lubricated and operates efficiently.

Understanding these ranges is crucial for pilots to monitor engine health during challenging flight conditions, as oil pressure that falls outside these limits could lead to potential engine complications or failures. Each of the other choices presents oil pressure ranges that are not aligned with the safety parameters established for aerobatic operations in the T-6A, making them insufficient or unsafe for such maneuvers.
