12.54.2 Describe the two common types of undercarriage system (tricycle/tail wheel).

There are two common types of undercarriage systems: tricycle and tail wheel.

1. Tricycle undercarriage:

In a tricycle undercarriage system, the aircraft has two main wheels located under the wings and a smaller wheel located at the front of the aircraft.

This configuration is commonly used in modern aircraft and provides better stability during takeoff and landing.

The nose wheel helps to keep the aircraft level during takeoff and landing and allows for better directional control.

2. Tail wheel undercarriage:

In a tail wheel undercarriage system, the aircraft has two main wheels located under the wings and a smaller wheel located at the rear of the aircraft.

This configuration was commonly used in older aircraft and provides less stability during takeoff and landing.

The tail wheel tends to be less stable and requires more skill to control during takeoff and landing.

However, tail wheel aircraft are often preferred by pilots who enjoy the challenge and excitement of flying a more traditional aircraft.
