Which statement best describes the function of the bogie in aircraft landing gear?

• A. It is the mounting point for the axles, wheels, and brake assemblies
• B. It houses the flight control computers
• C. It supports only the nose gear
• D. It lubricates the wheel bearings

Answer: (A)

In aircraft landing gear, the bogie is the subassembly that carries the wheel set. Its primary function is to provide a mounting platform for the axles, wheels, and brake assemblies, all attached to a rigid frame that sits on the gear leg. This arrangement allows the wheels to rotate freely, enables the brakes to apply properly, and distributes the landing loads across the wheel assembly into the strut. The bogie may also pivot or tilt to fit into the wheel well during retraction. It isn’t where flight control computers reside, it doesn’t specifically serve the nose gear, and it isn’t a lubrication component.
