What is the function of a cam incorporated in a nose gear shock strut?

The incorporation of a cam in the nose gear shock strut primarily serves to align the nosewheel. When the aircraft is in flight or during landing operations, the cam helps to ensure that the nosewheel is positioned correctly, which is vital for effective steering and directional control upon landing and during taxi operations. This feature is particularly important because a properly aligned nosewheel contributes to the stability of the aircraft and improves the pilot's ability to maneuver the aircraft safely on the ground.

In contrast, other options focus on different functions that are not directly related to the cam's role. For example, improving braking efficiency during landing pertains to the braking system itself rather than the alignment of the nosewheel. Shock absorption during takeoff focuses on the strut's ability to absorb forces but does not primarily involve the cam's function. Lastly, controlling inflation of the strut is associated with the maintenance of proper pressure but is independent of the cam's purpose in aligning the nosegear.
