What is weight-shift control aircraft?

Weight-shift control aircraft, also known as trikes or flex-wing aircraft, are a type of ultralight aircraft that uses a flexible wing and a suspended tricycle or conventional landing gear to control its direction of flight. These aircraft are classified in the United States under the Federal Aviation Administration (FAA) as Part 103 vehicles and typically weigh less than 254 pounds without fuel, pilot, and passenger.

In weight-shift control aircraft, the pilot controls the direction of flight by shifting their body weight in the seat, which changes the center of gravity of the aircraft. The control of the aircraft is achieved using two control handles, one for each wing, which allows the pilot to control the roll and pitch of the aircraft. The throttle and brakes are operated by the pilot's feet.

These aircraft are popular among recreational pilots because they are relatively easy to fly, with fewer controls and flight instruments than traditional aircraft. They are also more affordable than traditional aircraft, both in terms of purchasing and operating costs. They typically fly at lower speeds and lower altitudes, providing a unique flying experience with breathtaking panoramic views.

Weight-shift control aircraft are often used for sightseeing tours, aerial photography, and sport flying. Some models are available with two seats, allowing for a passenger or for flight instruction. However, due to their lightweight and unstable nature, weight-shift control aircraft can be more susceptible to weather and wind conditions than traditional aircraft, requiring pilots to be more careful and cautious during flight.
