In a hydraulic landing gear system, what is the purpose of crossfeed?

• A. To provide extra braking during landing.
• B. To speed gear extension.
• C. To allow pressure to be applied to all actuators if one path fails.
• D. To vent hydraulic fluid during retraction.

Answer: (C)

Crossfeed creates a bridge between hydraulic circuits so pressure can be shared from one path to another. This provides redundancy: if one line or actuator in the landing gear system develops a fault, the other path can still deliver hydraulic pressure to all actuators, allowing the gear to extend or retract reliably. It’s not about adding extra braking, speeding up the extension, or venting fluid during retraction.
