Tricycle gear refers to a type of aircraft landing gear configuration that features three wheels arranged in a triangular formation. Typically, this setup includes 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 a popular choice for many light aircraft. The tricycle gear configuration offers several advantages, such as improved visibility for pilots during taxiing and reduced risk of nose-over incidents. It is commonly used in various aircraft, including Cessna and Piper models, enhancing safety and ease of operation for pilots.
