What are the three basic types of landing gear generally used in aircraft?

• A. Tricycle, Conventional, Tandem
• B. Hybrid, Fixed, Retractable
• C. Single, Double, Triple
• D. Fixed, Moveable, Automated

Answer: (A)

The three basic types of landing gear typically used in aircraft are tricycle, conventional, and tandem configurations.

Tricycle landing gear consists of three wheels: one located under the nose or front of the aircraft, and two located under the wings or fuselage, which provides stability during takeoff and landing, helping to prevent the nose from tipping over. This configuration is commonly found in modern aircraft due to its ease of control and ground handling.

Conventional landing gear, also known as tailwheel gear, includes two main wheels located forward of the aircraft's center of gravity and a smaller tailwheel at the back. This design can sometimes present challenges in handling, particularly during takeoff and landing, but is favored for certain types of aircraft, particularly those designed for rougher operational environments.

Tandem landing gear is characterized by the arrangement of wheels that are situated along the centerline of the aircraft, typically used in specialized aircraft such as gliders and some military planes where weight distribution and aerodynamic considerations are critical.

Other options such as hybrid, fixed, retractable, single, double, and automated do not accurately reflect the commonly recognized standard types of landing gear found in aviation, as they either describe different characteristics or are specific to certain mechanisms or designs not categorized
