What are the four main subsystems that comprise the oil system in the T-6 aircraft?

The oil system in the T-6 aircraft consists of four main subsystems: pressure, scavenge, cooling, and breather systems. Each of these components plays a crucial role in ensuring the engine operates efficiently and reliably.

The pressure system is responsible for delivering pressurized oil to the engine's critical components, ensuring proper lubrication and cooling. The scavenge system works to remove used oil from those components, directing it back to the oil tank for reuse. The cooling system is essential for dissipating heat generated during engine operation, maintaining optimal oil temperatures to protect engine parts. Lastly, the breather system allows for proper ventilation of the oil tank, preventing the build-up of pressure and enabling the system to function effectively.

This combination of subsystems is integral to maintaining engine performance and longevity, allowing the T-6 aircraft to operate safely and efficiently. Other options, while they include components pertinent to oil management, do not accurately capture the primary subsystem components of the T-6 oil system.
