Tricycle gear is a type of landing gear used in aircraft, consisting of three wheels arranged in a triangular formation. Typically, there are two main wheels located under the wings and a smaller tail wheel at the rear. This design provides stability during takeoff and landing, making it easier for pilots to control the aircraft on the ground. The tricycle gear is popular in many small planes, such as those used for training or recreational flying. Unlike the traditional taildragger configuration, which has the main wheels in front and the tail wheel behind, the tricycle gear allows for better visibility and easier maneuvering on the runway.
