What type of landing gear system is described for the aircraft?

The description of the tricycle-type landing gear system is characterized by having two main wheels located at the rear and a steerable nose wheel. This configuration is popular in modern aircraft because it provides enhanced stability during takeoff and landing phases. The steerable nose wheel allows for easier directional control while taxiing, which is especially beneficial in crosswinds.

In this type of setup, the main wheels bear the weight of the aircraft, while the nose wheel offers support and maneuverability. This arrangement helps to maintain a favorable center of gravity and reduces the risk of tipping over during landing, making it an advantageous design for both pilots and the structural integrity of the aircraft.

The other options refer to different types of landing gear systems that do not match the characteristics of a tricycle-type system. For instance, tailwheel types typically have their main wheels located ahead of the center of gravity, while conventional gear designs include one main wheel and a tail wheel, which can lead to more challenging ground handling. Lastly, a fixed gear with no shock absorption is a limited design that does not offer the benefits of iffy landing and takeoff scenarios as effectively as a tricycle gear.
