Which of the following is NOT a feature of conventional landing gear?

Conventional landing gear typically features a main wheel configuration that includes two wheels positioned at the front of the aircraft and a single wheel located at the tail or rear. This design is aimed at improving stability during takeoff and landing, which is why increased stability on takeoff is a recognized characteristic.

The unique layout of conventional landing gear allows for a more straightforward approach to landing, facilitating a proper angle of descent and providing immediate control upon touchdown. The front wheels bear the bulk of the aircraft's weight and assist with directional control, while the rear wheel supports the tail and balances the aircraft.

Independently movable wheels are not a feature of conventional landing gear, as this type typically employs fixed landing gear configurations. In contrast, some advanced designs might use retractable or independently moving systems, primarily found in modern aircraft with tricycle configurations. Thus, the option regarding independently movable wheels is correctly identified as not being a feature of conventional landing gear.
