    5 km flight visibility, 1500 m horizontally from cloud, 1000 ft (300m) vertically from cloud. At or below 3,000 ft: 5 km flight visibility, clear of cloud and in sight of the surface or, for an aircraft, other than a helicopter, operating at 140 kt or less: 1,500 m flight visibility, clear of cloud and in sight of the surface For helicopters:

  3. Airspace class (United States) - Wikipedia

    en.wikipedia.org/wiki/Airspace_class_(United_States)

    VFR visibility and cloud clearance requirements are the same as for class C and D airspaces when below 10,000 feet (3,000 m) MSL. Above 10,000 ft MSL, the visibility requirement is extended to 5 miles (8 km) and the cloud clearance requirement is extended to 1,000 feet (300 m) below clouds, 1,000 feet (300 m) above, and 1 mile (1.6 km) laterally.

  4. Visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Visual_flight_rules

    Under visual meteorological conditions, the minimum visual range, distance from clouds, or cloud clearance requirements to be maintained above ground vary by jurisdiction, and may also vary according to the airspace in which the aircraft is operating. [4] In some countries, VFR flight is permitted at night, and is known as night VFR.

    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). However, most of the ...

  6. VFR over-the-top - Wikipedia

    en.wikipedia.org/wiki/VFR_Over-The-Top

    The Canadian rules specify that an aircraft may be operated in VFR OTT flight during the cruise portion of the flight during the day, at a vertical distance from clouds of at least 1000 feet. When the aircraft is operated between two cloud layers, the vertical distance between the layers must be at least 5000 feet.

    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.

  8. List of Class B airports in the United States - Wikipedia

    en.wikipedia.org/wiki/List_of_Class_B_airports...

    Class B is a class of airspace in the United States which follows International Civil Aviation Organization (ICAO) airspace designation. Class B airspace areas are designed to improve aviation safety by reducing the risk of midair collisions in the airspace surrounding airports with high-density air traffic operations. [1]

    These routes include “VFR Flyway”, “VFR Corridor”, and “Class B Airspace VFR Transition Route”. [7]: 3-5-5 VFR Flyway: a general flight path in planning flights inside or near complex terminal airspace to avoid Class B airspace. ATC clearances are not required. VFR corridor: defined corridor through class B airspace.
