Taxiway centerlines are enhanced for 150 feet (46 m) before a runway holding position marking. The enhanced taxiway centerline is standard [4] at all FAR Part 139 certified airports in the US. Taxiway Edge Markings Used to define the edge of the taxiway when the edge does not correspond with the edge of the pavement.
According to ICAO, airport diagrams shall show coordinates, field elevations, runways, aprons, taxiways, hot spots, taxiway routes, air transit routes, lighting, air traffic control (ATC) service boundary, communication channels, obstacles, slope angles, buildings and service areas, VOR checkpoints, and movement area permanently unsuitable for aircraft.
There are standards for runway markings. [22] The runway thresholds are markings across the runway that denote the beginning and end of the designated space for landing and takeoff under non-emergency conditions. [23] The runway safety area is the cleared, smoothed and graded area around the paved runway. It is kept free from any obstacles that ...
A portion of the runway behind a displaced threshold has three markings: [1] White arrows along the center line of the runway; White arrow heads across the width of the runway just prior to the displaced threshold bar; A 10 feet (3.0 m) wide white threshold bar across the width of the runway at the displaced threshold
A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately 300 metres (980 ft) beyond the landing threshold of the runway.
The airport apron, apron, flight line, or ramp is the area of an airport where aircraft are parked, unloaded or loaded, refueled, boarded, or maintained. [1] [2] [3] Although the use of the apron is covered by regulations, such as lighting on vehicles, it is typically more accessible to users than the runway or taxiway. However, the apron is ...
White space around the chart is filled with map information and the legend, scales, and tables of airport and airspace information. Terrain is color-coded for its elevation and major roads, cities, and bodies of water are shown for visual reference, as well as other identifiable structures (e.g., stadiums and water towers ).
The horizontal white dumb-bell but with a black bar placed perpendicular to the shaft across each circular portion of the dumb-bell when displayed in a signal area indicates that aircraft are required to land and take off on runways only, but other manoeuvres need not be confined to runways and taxiways.
