61runway and terrain slopes illusion — An illusion caused by an up sloping runway, up sloping terrain, or both during an approach for landing. The pilot perceives that the aircraft is at a higher altitude than it actually is and thus tends to fly a lower approach. A down sloping… …
62runway configuration — A layout or design of a runway(s), where operations on the particular runway(s) being used at a given time are mutually dependent. A large airport can have two or more runway configurations operating simultaneously. Some of the configurations are …
63runway marking — There are three types of markings on civil airfields: visual, nonprecision instrument, and precision instrument. Military airfields may use abbreviated markings in some cases. The basic markings on runways used for operations under VFR (visual… …
64runway overrun — A stabilized or paved area beyond the end of the runway of the same width as the runway plus shoulders, centered on the extended runway centerline …
65runway acceptance rate — The number of aircraft that can land on and depart from a runway consistent with the runway and aerodrome conditions during a specified period of time …
66runway aiming point marking — The aiming point marking serves as a visual aiming point for a landing aircraft. These two rectangular markings consist of a broad white stripe located on each side of the runway centerline and approximately 1,000 ft from the landing threshold.… …
67runway alignment indicator lights — This airport lighting facility in the terminal area consists of five or more sequenced flashing lights installed on the extended center line of the runway. The maximum spacing between lights is 200 ft, extending from 1600 to 3000 ft from the… …
68runway bearing — The magnetic or true bearing of the runway centerline as measured from magnetic or true north. See runway heading …
69runway clear zone — An area at ground level whose perimeter conforms to the runway’s innermost approach surface projected vertically. It begins at the end of the primary surface, and it terminates directly below the point(s) where the approach surface reaches a… …
70runway direction number — A whole number to the nearest one tenth of the magnetic bearing of the runway and measured in degrees clockwise from magnetic north. See runway heading …
