What portion of the landing gear strut should be visible during a preflight inspection?

During a preflight inspection, the visibility of certain portions of the landing gear strut is critical for ensuring the aircraft is ready for safe operation. The correct choice indicates that 2.6 inches of the main gear strut should be visible. This visibility is essential as it signifies proper extension of the gear and indicates that the shock strut is not under-inflated or has not lost hydraulic fluid, both of which can compromise landing gear performance.

In aviation, different aircraft may have different requirements for the visible portion of the landing gear strut. For this specific aircraft type, the 2.6 inches on the main gear serves as a manufacturer’s guideline that promotes safety and performance integrity during flight operations.

While the other options pertain to different measurements for different components of the landing gear, none align with the established standard for the main gear strut in this case. It’s vital for pilots to familiarize themselves with their specific aircraft’s maintenance and preflight inspection requirements to ensure that all components are functioning correctly and safely.
