    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 ...

  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.

[7] [3] 1201 US: Assigned via FAR 93.95 for use by VFR aircraft in the immediate vicinity of LAX.

    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).

    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]

    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.

    Pilots are required to maintain night currency every 90 days to carry passengers at night. Specifically, 61.57(b) states that "...no person may act as pilot in command of an aircraft carrying passengers during the period beginning 1 hour after sunset and ending 1 hour before sunrise, unless within the preceding 90 days that person has made at least three takeoffs and three landings to a full ...
