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.
An Airbus A330-300 of Turkish Airlines on short final to Heathrow Airport, immediately before landing. An airfield traffic pattern is a standard path followed by aircraft when taking off or landing while maintaining visual contact with the airfield. At an airport, the pattern (or circuit) is a standard path for coordinating air traffic. It ...
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.
Washington Dulles International Airport Metadata This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.
The airport diagrams are part of the Aeronautical Information Publication (AIP) which is updated on a 28-day cycle as per the ICAO.For the FAA's digital - Terminal Procedures Publication/Airport Diagrams, this causes a change in the URL involving four numbers: the first two represent the year (09 for 2009, 10 for 2010) and the second two represent the current AIRAC cycle (01 through 13).
A localizer type directional aid (LDA) or Instrument Guidance System (IGS) is a type of localizer-based instrument approach to an airport. It is used in places where, due to terrain and other factors, the localizer antenna array is not aligned with the runway it serves.
The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...
