Airport & Runway Information
Term | Definition |
---|---|
runway | A strip on which aircraft can take off and land; it is part of the maneuvering or movement area, which also includes taxiways and other areas controlled by the air traffic control tower. |
Runway surfaces | Composed of manmade materials (usually asphalt, concrete, or a mixture) or natural ones, such as grass, dirt, or gravel. |
Runway names | named fomr 01-36 for a one-tenth value of their heading or direction, rounded to the nearest 10 degrees- So runway pointing (90degrees) would be "runway 09", a runway pointing west(270degrees) would be "runway 27". |
Magnetic North | follows magnetic north pole, it moves 5 to 24 miles per year becuase of currents inthe magma far below the earth's surface. |
Fixed aircraft landing/take off | Usually try to take off and land into the wind to increase air flow over the wings and thereby increase lift, at the same time decreasing the ground speed needed. |
Runway size | can vary form general aviation airpots as small as 800 feet (244 m) long and 26 feet (8 m) wide to international airports as large as 18,00 feet (5,500 m) long and 260 feet( 80m ) wide. At sea level, a 10,000 foot (3,00 m) runway can land virtually any ai |
Type of Runway: visual | Visual runways such as those at small airstrips usually have no markings, but they may have threshold markings, designators, and centerlines. They do not provide an instrument-based landing procedure- pilots must be able to see the runway to use it. Also, |
Type of Runway: Nonprecision instrument runway. | most often seen at small- to medium size airports. runways may be marked with threshold markings, designators, centerlines, and sometimes a 1,0-0 foot (304.80 km) or 1,500 foot (457.20 km) mark known as an aiming point. They provide horizontal position gu |
Approach Lighting System (ALS) | A series of lightbars, strobe lights, or a combination of the two that extends outward from the approach end of the runway. |
Runway End Identification Lights (REIL) | a pair of synchronized flashing lights installed at the runway threshold, one on each side. They can face the approach direction or be omnidirectional (visible from all directions). They enhance identification of a runway surrounded by other lighting or l |
Runway end lights | A pair of four lights on each side of precision instrument runways, extending the full width of the runway. These lights show green when viewed by approaching aircraft and red when seen from the runway to indicate the end of the runway to a departing airc |
Runway edge lights | white elevated lights running the lenght of the runway on both sides. On precision instrument runways, the edge lighting beomces yellow in the last 2,00 feet (610 m) or half the runway length, whichever is greater. Taxiways are differentiated by being bor |
Runway Centerline Lighting System (RCLS) | white lights embedded in the surface of the runway along the centerline at 50-foot (15 m) intervals, changing to alternating red and white 3,00 feet (915m) from the ened of the runway, and then to red for the last 1,000 feet (305 m ). |
