    Visual flight rules (VFR) flight standard squawk code used in North American airspace when no other has been assigned or is applicable. [7] [3] 1201 US: Assigned via FAR 93.95 for use by VFR aircraft in the immediate vicinity of LAX. [3] US (Visual flight rules (VFR) glider operations for gliders not in contact with ATC, through February 2012 ...

  3. 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.

    In this example, the transponder code selected is 1200 for VFR flight (in North American airspace). The green IDENT button is marked "ID". The green IDENT button is marked "ID". A transponder (short for trans mitter-res ponder [ 1 ] and sometimes abbreviated to XPDR, [ 2 ] XPNDR, [ 3 ] TPDR [ 4 ] or TP [ 5 ] ) is an electronic device that ...

  5. 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.

  6. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    VFR pilots may use cockpit instruments as secondary aids to navigation and orientation, but are not required to; the view outside of the aircraft is the primary source for keeping the aircraft straight and level (orientation), flying to the intended destination , and avoiding obstacles and hazards (separation).

  7. Special visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Special_visual_flight_rules

    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. [5] Note that an aircraft might be able to fly under SVFR even in Class A airspace, where instrument flight rules (IFR) flight is the norm. [6]

  8. Equipment codes - Wikipedia

    en.wikipedia.org/wiki/Equipment_codes

    For example, if a desired route requires GPS, then the pilot should file /G, even if the aircraft also qualifies for other suffixes (this may be moot due to new RNAV routing requirements to use the ICAO form & codes). Pilots are recommended to file the maximum capability of their aircraft in the equipment suffix.

  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.
