Taxiing is the controlled movement of an aircraft along the airport surface, usually moving between the runway and the parking apron. Pilots use the aircraft engines for propulsion and steer using a tiller or rudder pedals, which control the nose wheel. This phase of operation requires strict adherence to ground control clearances to avoid runway incursions or collisions with ground equipment.
