  2. Runway - Wikipedia

    en.wikipedia.org/wiki/Runway

    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. [28] The runway safety area is the cleared, smoothed and graded area around the paved runway. It is kept free from any obstacles that might impede flight or ground roll of aircraft.

    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 ).

  4. Airfield traffic pattern - Wikipedia

    The purpose of this is to provide arriving aircraft with the best runway to land on according to the wind direction. Runway orientation is determined from historical data of the prevailing winds in the area. This is especially important for single-runway airports that do not have the option of a second runway pointed in an alternative direction.

  5. Runway visual range - Wikipedia

    en.wikipedia.org/wiki/Runway_visual_range

    A pilot's view of Lisbon Airport's runway 21 in fog; runway visual range is about 200 m (660 ft). In aviation, the runway visual range (RVR) is the distance over which a pilot of an aircraft on the centreline of the runway can see the runway surface markings delineating the runway or the lights delineating the runway or identifying its centre line.

  6. Precision approach path indicator - Wikipedia

    en.wikipedia.org/wiki/Precision_Approach_Path...

    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.

  7. Aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart

    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 ...

  8. Runway Awareness and Advisory System - Wikipedia

    en.wikipedia.org/wiki/Runway_Awareness_and...

    The Runway Awareness and Advisory System (RAAS) is an electronic detection system that notifies aircraft flight crews on the ground of their position relative to their allocated runway. It is a type of Runway Situation Awareness Tool (RSAT).

  9. Flight planning - Wikipedia

    en.wikipedia.org/wiki/Flight_planning

    Brake release weight is the weight of an aircraft at the start of a runway, just prior to brake release for takeoff. This is the ramp weight minus any fuel used for taxiing. Major airports may have runways that are about 2 miles (3 km) long, so merely taxiing from the terminal to the end of the runway might consume up to a ton of fuel.
