Which of the following is NOT typically considered a major component of a tricycle landing gear?

• A. Retractable tail wheel.
• B. Nose gear assembly.
• C. Gear doors with retraction actuators.
• D. Main gear assemblies with struts and wheels.

Answer: (A)

In a tricycle landing gear setup, you typically have two main gear assemblies under the wings or fuselage and a nose gear at the front to support and steer the aircraft on the ground. The main gear with their struts and wheels carry the bulk of the load during landing and taxi, while the nose gear handles steering and directional control. Gear doors with retraction actuators are essential for retractable systems, opening to allow the gear to extend and then closing to smooth the aerodynamics when the gear is up. A retractable tail wheel, however, belongs to a taildragger configuration and is not part of the typical tricycle arrangement. That’s why it’s not considered a major component of tricycle landing gear.
