Taxiing (rarely spelled taxying) [1] is the movement of an aircraft on the ground, under its own power, in contrast to towing or pushback where the aircraft is moved by a tug. The aircraft usually moves on wheels, but the term also includes aircraft with skis or floats (for water-based travel).
It is a higher-risk procedure, as pilots may not see, or hear the radio transmissions from, aircraft taxiing on the runway. [ 3 ] At controlled airports, take-off or landing clearances do not authorize the pilot to reverse course and backtrack along the runway, unless specified by air traffic control.
Runway Holding Position Markings These show where an aircraft should stop when approaching a runway from a taxiway. They consist of four yellow lines, two solid and two dashed, spaced six or twelve inches (15 or 30 cm) apart, and extending across the width of the taxiway or runway.
Intersecting Taxiway: before the intersection with a taxiway that will have other aircraft taxiing for takeoff or parking. Point on Runway: before a designated point. This is the newest type, used when safety precautions are needed due to hazards concerning other runways or taxiways, or hazards for a landing plane on its runway (ice, for instance).
Runway 13R at Palm Springs International Airport An MD-11 at one end of a runway. In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. [1] Runways may be a human-made surface (often asphalt, concrete, or a mixture of both) or a natural surface (grass, dirt, gravel, ice, sand or salt).
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
A United Airlines flight rolled off the runway at a Houston airport Friday morning, the airline said in a statement. The Boeing 737 plane had landed at George Bush Intercontinental Airport around ...
Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground to flying in the air, usually starting on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier), no runway is needed. Takeoff is the opposite of landing.
