  2. 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 ...

  3. Air navigation - Wikipedia

    en.wikipedia.org/wiki/Air_navigation

    A private pilot planning a flight under VFR will usually use an aeronautical chart of the area which is published specifically for the use of pilots. This map will depict controlled airspace, radio navigation aids and airfields prominently, as well as hazards to flying such as mountains, tall radio masts, etc. It also includes sufficient ground ...

  4. National Airspace System - Wikipedia

    en.wikipedia.org/wiki/National_Airspace_System

    National Airspace System. The National Airspace System (NAS) is the airspace, navigation facilities and airports of the United States along with their associated information, services, rules, regulations, policies, procedures, personnel and equipment. [1] It includes components shared jointly with the military.

  5. Aeronautical chart conventions (United States) - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart...

    A sectional chart is a two-sided chart created from a Lambert Conformal Conic Projection [1] with two defined standard parallels. The scale is 1:500,000, with a contour interval of 500 feet. The size of each sectional is designed to be "arm's width" when completely unfolded. The "northern" half of the section is on one side of the chart, and ...

  6. Sectional aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Sectional_aeronautical_chart

    A sectional chart shows topographical features that are important to aviators, such as terrain elevations, ground features identifiable from altitude (rivers, dams, bridges, buildings, etc.), and ground features useful to pilots (airports, beacons, landmarks, etc.). The chart also shows information on airspace classes, ground-based navigation ...

  7. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    The transition layer is the airspace between the transition altitude and the transition level. According to these definitions the transition layer is 0–500 feet (0–150 m) thick. Aircraft are not normally assigned to fly at the "'transition level'" as this would provide inadequate separation from traffic flying on QNH at the transition altitude.

  8. Lambert conformal conic projection - Wikipedia

    en.wikipedia.org/wiki/Lambert_conformal_conic...

    Aeronautical chart on Lambert conformal conic projection with standard parallels at 33°N and 45°N. A Lambert conformal conic projection (LCC) is a conic map projection used for aeronautical charts, portions of the State Plane Coordinate System, and many national and regional mapping systems. It is one of seven projections introduced by Johann ...

  9. North Atlantic Tracks - Wikipedia

    en.wikipedia.org/wiki/North_Atlantic_Tracks

    North Atlantic Tracks for the westbound crossing of February 24, 2017, with the new RLAT Tracks shown in blue. The North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), are a structured set of transatlantic flight routes that stretch from eastern North America to western Europe across the Atlantic Ocean, within the North Atlantic airspace region.
