  2. 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 ...

  3. Approach plate - Wikipedia

    en.wikipedia.org/wiki/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.

  4. 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 ...

  5. Aircraft approach category - Wikipedia

    en.wikipedia.org/wiki/Aircraft_approach_category

    Additional speed ranges are specified for other segments of the approach. [1]: Table II-5-1-2 Approach plates generally include visibility requirements up to category D. [1]: II-5-1-3 While ICAO specify a top speed of 391 km/h for Category E, there exist no aircraft with an approach speed above this.

  6. Marker beacon - Wikipedia

    en.wikipedia.org/wiki/Marker_beacon

    A back course marker (BC) normally indicates the ILS back-course final-approach fix where approach descent is commenced. It is identified by pairs of Morse-code "dots" at 3000 Hz (95 pairs per minute), which will trigger the white light on a marker beacon indicator, but with a different audio rhythm from an inner marker or en-route marker.

  7. Instrument landing system localizer - Wikipedia

    en.wikipedia.org/wiki/Instrument_landing_system...

    Localizer as component of an ILS (KMEZ runway 27, Mena, Arkansas) Emission patterns of the localizer and glide path signals. An instrument landing system localizer, or simply localizer (LOC, [1] or LLZ prior to 2007 [2]), is a system of horizontal guidance in the instrument landing system, which is used to guide aircraft along the axis of the runway.

  8. Instrument flight rules - Wikipedia

    en.wikipedia.org/wiki/Instrument_flight_rules

    Practicing instrument approaches can be done either in the instrument meteorological conditions or in visual meteorological conditions – in the latter case, a safety pilot is required so that the pilot practicing instrument approaches can wear a view-limiting device which restricts his field of view to the instrument panel. A safety pilot's ...
