Tricycle landing gear
Tricycle gear is a type of aircraft undercarriage, or landing gear, arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest to take-off, land and taxi, and consequently the configuration is the most widely used on aircraft.
