51runway threshold marking — Markings placed to indicate longitudinal limits of that portion of the runway usable for landing. They consist of long vertical lines 100 ft (30 m) long and 3 ft (1 m) wide and are placed just short of runway designation markings. They consist… …
52runway visual range — The maximum distance in the direction of takeoff or landing at which the runway, or specified lights or markers delineating it, can be seen from a position above a specified point on its centerline at a height corresponding to the average eye… …
53Runway Awareness and Advisory System — The Runway Awareness and Advisory System (RAAS) is an electronic detection system developed by the American electronics company Honeywell. It provides aircraft flight crews with information concerning the aircraft s position relative to an… …
54runway length — i. As it pertains to landing, the measured length from the threshold to the end of the runway. ii. As it pertains to takeoff, the measured length from where the takeoff is designated to begin to the end of the runway. Runway lights. iii.… …
55runway lights — Lights having a prescribed angle of emission used to define the lateral limits of runway. The intensity of runway lights may be controllable, or it may be preset. Runway lights are placed uniformly on both sides of the runway at 200 ft (60 m)… …
56runway obstacle-free zone — A defined volume of airspace centered above the runway whose elevation at any point is the same as the elevation of the nearest point on the runway centerline. The runway obstacle free zone (OFZ) extends 200 ft beyond each end of the runway. The… …
57runway profile descent — An IFR (instrument flight rules) air traffic arrival to a runway procedure published for pilot use in graphic and/or textural form. It may be associated with a standard terminal arrival. Runway profile descents may depict crossing altitudes,… …
58runway-visibility value — The visibility determined for a particular runway by a transmissometer. A transmissometer provides a continuous indication of the visibility (reported in miles or fractions of miles) for the runway. RVV is used in lieu of prevailing visibility in …
59runway-width illusion — A narrower than usual runway can create the illusion that the aircraft is at a higher altitude than it actually is. The pilot who does not recognize this illusion will fly a lower approach, with the risk of striking objects along the approach… …
60runway width — The width of a runway is dependent on the normal prevalent visibility, maneuverability, and stability of aircraft during landing. Runway widths recommended by ICAO Runway design characteristics (FAA) Values of runway widths recommended by the… …
