    These alphabetic codes are used on FAA and ICAO flight plan forms to aid flight service station (FSS) personnel in their handling of aircraft. On the FAA domestic flight plan form (FAA Form 7233-1) the equipment code is a single character placed in block 3 (Aircraft Type / Special Equipment) as a suffix to the aircraft type code. A single ...

  6. Visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Visual_flight_rules

    VFR requires a pilot to be able to see outside the cockpit to control the aircraft's altitude, navigate, and avoid obstacles and other aircraft. [3] Governing agencies establish specific requirements for VFR flight, including minimum visibility, and distance from clouds, to ensure that aircraft operating under VFR are visible from enough distance to ensure safety.

  7. Special visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Special_visual_flight_rules

    Flight under SVFR is only allowed in controlled airspace, and always requires clearance from air traffic control (ATC). [4] It usually happens when the aircraft is inside controlled airspace, and the local weather is less than the minimums required for flight under visual flight rules (VFR) within the airspace in question.

    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).

    These codes are defined by both the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA). ICAO codes are published in ICAO Document 8643 Aircraft Type Designators [1] and are used by air traffic control and airline operations such as flight planning. While ICAO designators are used to ...
