Which of the following is NOT a subsystem of the BAK-12 hydraulic system?

The BAK-12 hydraulic system, commonly used in aviation hydraulic setups, comprises various subsystems that work together to facilitate hydraulic operations. The components integral to its function typically include systems that manage braking, static functions, and rewind mechanisms.

The power system, while crucial in many hydraulic applications, is not classified as a subsystem of the BAK-12 specifically. Instead, it typically refers to the broader energy supplying and converting elements necessary for hydraulic operation, such as pumps or motors, which are vital in providing hydraulic power but do not fall within the designated subsystems of the BAK-12.

Understanding these classifications is essential for effectively working with hydraulic systems, as it helps clarify how each functional component operates within the overall system and allows for better troubleshooting and maintenance strategy regarding the BAK-12 hydraulic system.
