Which two components hold the nose gear in the down position?

• A. Over center folding struts and a mechanical brake on the electric actuator
• B. Hydraulic lock and manual pin
• C. Magnetic latch and hydraulic pin
• D. Spring-loaded hook and nylon strap

Answer: (A)

Two mechanisms provide a secure hold when the nose gear is down. First, the nose gear strut uses an over-center folding arrangement that passes through a center point and becomes self-locking in the extended position. This geometry means the leg naturally resists retraction once fully extended. Second, there is a mechanical brake on the electric actuator that moves the gear, which clamps and prevents motion of the actuator to retract the gear. Together, these give positive, redundant locking in the down position so the nose gear stays down during landing and taxiing. The other described devices aren’t used in this system for keeping the nose gear down.
