  2. Visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Visual_flight_rules

    VFR cruising altitude rules in the US and Canada [ edit ] In the US, there are specific VFR cruising altitudes, based on the aircraft's course, to assist pilots in separating their aircraft while operating under visual flight above 3,000 ft above the surface (AGL) but below 18,000 ft Mean Sea Level (MSL).

  3. 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.

  4. Separation (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Separation_(aeronautics)

    Separation at cruising altitude (aircraft passing below). Air traffic controllers apply rules, known as separation minima, to do this. Pairs of aircraft to which these rules have been successfully applied are said to be separated: the risk of these aircraft colliding is therefore remote.

  5. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". In metre altitudes the format is Flight Level xx000 metres. Flight levels are usually designated in writing as FLxxx, where xxx is a two- or three-digit number indicating the pressure altitude in units of 100 feet (30 m). In radio communications, FL290 ...

  6. VFR-on-top - Wikipedia

    en.wikipedia.org/wiki/VFR-on-Top

    VFR over-the-top is different from VFR-on-top, in that VFR-on-top is an IFR clearance that allows the pilot to fly VFR altitudes, while VFR over-the-top is strictly a VFR operation in which the pilot maintains VFR cloud clearance requirements while operating on top of an undercast layer. [2]

  7. Visual flight - Wikipedia

    en.wikipedia.org/wiki/Visual_flight

    [citation needed] Regulations for visual flights are under a separate set of visual flight rules. [ 1 ] The pilot can maintain or change the airspeed , altitude , and direction of flight ( heading ) as well as the rate of climb or rate of descent and rate of turn ( bank angle ) through the use of the aircraft flight controls and aircraft engine ...

  8. Maximum elevation figure - Wikipedia

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    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. It is of interest to pilots, who want to be aware of the highest mountain peaks and tall towers nearby, so that they can fly above them to avoid controlled flight into ...

  9. 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.
