What problems will be encountered with HYD 2 LO PRESS message displayed?

• A. Nose gear will not extend and a sideslip may be required to achieve MLG down lock.
• B. Nose gear will extend normally with no sideslip required.
• C. Nose gear will retract during landing.
• D. There will be no impact on MLG down lock.

Answer: (A)

When HYD 2 LO PRESS appears, hydraulic system 2 does not have enough pressure to power the nose landing gear extension and its down-lock mechanism. That means the nose gear may not extend at all, or may not reach the fully down-and-locked position. If the nose gear can’t properly align with the down-lock path, you might need a sideslip to help position the aircraft so the down-lock can engage and secure the nose gear in the extended position. This directly links the low hydraulic pressure to both failure to extend and the potential need for lateral maneuvering to achieve a secure down lock. The other outcomes—normal extension, retraction, or no impact—don’t fit the effect of a hydraulic pressure fault on the gear extension system.
