  2. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    In the US, weather conditions are forecast broadly as VFR, MVFR (marginal visual flight rules), IFR, or LIFR (low instrument flight rules). [ 11 ] The main purpose of IFR is the safe operation of aircraft in instrument meteorological conditions (IMC).

  3. Visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Visual_flight_rules

    If the weather is less than VMC, pilots are required to use instrument flight rules, and operation of the aircraft will be primarily through referencing the instruments rather than visual reference. In a control zone, a VFR flight may obtain a clearance from air traffic control to operate as Special VFR. [2]

  4. Aeronautical chart conventions (United States) - Wikipedia

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

    The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration". The legend of an aeronautical chart lists many of the symbols, colors and codes used to convey information to the map reader.

  5. Maximum elevation figure - Wikipedia

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    MEF's of 4700 and 3300 feet are shown on this excerpt from the FAA's Los Angeles sectional aeronautical chart. Maximum elevation figure (MEF) is a type of visual flight rule (VFR) information that indicates the elevation of the highest geographical feature within a GEOREF quadrangle area.

  6. Sectional aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Sectional_aeronautical_chart

    In United States aviation, a sectional aeronautical chart, often called a sectional chart or a sectional for short, is a type of aeronautical chart designed for air navigation under visual flight rules (VFR). In Australia, Canada and some other countries, the equivalent charts used for visual flight are called VFR Navigation Charts (VNCs).

  7. Visual meteorological conditions - Wikipedia

    en.wikipedia.org/wiki/Visual_meteorological...

    VFR / VMC visibility requirements in the US. In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft.

  8. Lambert conformal conic projection - Wikipedia

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

    Pilots use aeronautical charts based on LCC because a straight line drawn on a Lambert conformal conic projection approximates a great-circle route between endpoints for typical flight distances. The US systems of VFR (visual flight rules) sectional charts and terminal area charts are drafted on the LCC with standard parallels at 33°N and 45 ...

  9. Terminal area chart - Wikipedia

    en.wikipedia.org/wiki/Terminal_area_chart

    FAA-Terminal Area Chart Baltimore-Washington from 2011. Like the VFR sectional charts that they complement, terminal area charts depict topographic features and other information of interest to aviators flying visually, including major landmarks, terrain elevations, visual navigation routes, ground-based navigation aids, airports, rivers, cities, and airspace boundaries.
