What do lockout deboosters primarily function as?

Lockout deboosters primarily function as pressure reducing valves. Their main purpose is to control and reduce system pressure in hydraulic systems, particularly in cases where the hydraulic pressure needs to be managed more effectively to prevent overstress on components.

When a lockout debooster is activated, it reduces the pressure for a specific part of the system, ensuring that the system operates safely and efficiently under various operating conditions. This function is critical in landing gear systems where hydraulic pressure must be carefully managed to facilitate safe operation during landing and takeoff.

In contrast, other options do not align with the core role of lockout deboosters. A full flow control valve would regulate fluid flow but not specifically reduce pressure. A fluid distribution mechanism focuses on directing hydraulic fluid rather than managing pressure levels. An emergency braking system serves a different purpose related to safety rather than pressure reduction.
