  2. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    In controlled airspace, air traffic control (ATC) separates IFR aircraft from obstacles and other aircraft using a flight clearance based on route, time, distance, speed, and altitude. ATC monitors IFR flights on radar, or through aircraft position reports in areas where radar coverage is not available. Aircraft position reports are sent as ...

    en.wikipedia.org/wiki/List_of_Transponder_Codes

    Instrument Flight Rules (IFR) flight below 18,000 ft ASL when no other code has been assigned. [7] ICAO: Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A ...

  4. Equipment codes - Wikipedia

    en.wikipedia.org/wiki/Equipment_codes

    An equipment code describes the communication (COM), navigation (NAV), approach aids and surveillance transponder equipment on board an aircraft.These alphabetic codes are used on FAA and ICAO flight plan forms to aid flight service station (FSS) personnel in their handling of aircraft.

  5. CRAFT (aviation) - Wikipedia

    The initial altitude is sometimes stated on the charts. If not, it will be given by the air traffic controller. The departure frequency is given to the pilot when ATC hands the aircraft over to the next sector. A typical IFR clearance would be: OOABC, cleared to Ostend via the DENUT 7C departure, climb flight level six zero, squawk four six ...

  6. En-route chart - Wikipedia

    en.wikipedia.org/wiki/En-route_chart

    An en-route (also known as en route [1] or enroute [2]) chart provides detailed information useful for instrument flight, including information on radionavigation aids (navaids) such as VORs and NDBs, navigational fixes (waypoints and intersections), standard airways, airport locations, minimum altitudes, and so on.

    [6] [7] For flights on instrument flight rules (IFR), the squawk code is typically assigned as part of the departure clearance and stays the same throughout the flight. [6] [7] Flights on visual flight rules (VFR), when in uncontrolled airspace, will "squawk VFR" (1200 in the United States and Canada, 7000 in Europe). Upon contact with an ATC ...

  9. Standard terminal arrival route - Wikipedia

    en.wikipedia.org/wiki/Standard_terminal_arrival...

    In aviation, a standard terminal arrival route (STAR) is a published flight procedure followed by aircraft on an instrument flight rules (IFR) flight plan just before reaching a destination airport. A STAR is an air traffic control (ATC)-coded IFR arrival route established for application to arriving IFR aircraft destined for certain airports.
