  2. Instrument approach - Wikipedia

    en.wikipedia.org/wiki/Instrument_approach

    An "approach plate" depicting an instrument approach procedure for an ILS approach to Tacoma Narrows Airport in the United StatesIn aviation, an instrument approach or instrument approach procedure (IAP) is a series of predetermined maneuvers for the orderly transfer of an aircraft operating under instrument flight rules from the beginning of the initial approach to a landing, or to a point ...

  3. Instrument landing system - Wikipedia

    en.wikipedia.org/wiki/Instrument_landing_system

    ILS planes. An instrument landing system operates as a ground-based instrument approach system that provides precision lateral and vertical guidance to an aircraft approaching and landing on a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorological conditions (IMC), such as low ceilings or reduced ...

  4. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    The approach portion of an IFR flight may begin with a standard terminal arrival route (STAR), describing common routes to fly to arrive at an initial approach fix (IAF) from which an instrument approach commences. An instrument approach terminates either by the pilot acquiring sufficient visual reference to proceed to the runway, or with a ...

  5. Approach plate - Wikipedia

    en.wikipedia.org/wiki/Approach_plate

    Approach plate. An approach plate for the ILS or LOC approach to runway 14L at Cologne Bonn Airport, Germany. Approach plates (or, more formally, instrument approach procedure charts) are the printed or digital charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations.

  6. 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.

  7. PANS-OPS - Wikipedia

    en.wikipedia.org/wiki/PANS-OPS

    PANS-OPS. PANS-OPS is an air traffic control acronym which stands for Procedures for A ir N avigation Services – Aircraft OPerationS. PANS-OPS are rules for designing instrument approach and departure procedures. Such procedures are used to allow aircraft to land and take off when instrument meteorological conditions (IMC) impose instrument ...

  8. Localizer performance with vertical guidance - Wikipedia

    en.wikipedia.org/wiki/Localizer_Performance_with...

    Localizer performance with vertical guidance (LPV) are the highest precision GPS (SBAS enabled) aviation instrument approach procedures currently available without specialized aircrew training requirements, such as required navigation performance (RNP). Landing minima are usually similar to those of a Cat I instrument landing system (ILS), that ...

  9. Approach lighting system - Wikipedia

    en.wikipedia.org/wiki/Approach_lighting_system

    An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end. [1] ALS usually serves a runway that has an instrument approach procedure (IAP) associated with it and allows the ...
