  2. Localizer type directional aid - Wikipedia

    en.wikipedia.org/wiki/Localizer_Type_Directional_Aid

    As a "directional aid", and only a Category I (CAT I) approach, rather than a full-fledged instrument landing system (ILS), the LDA is more commonly used to help the pilot safely reach a point near the runway environs, where he or she hopefully can see the runway, at which point he or she will proceed and land visually, as opposed to (for ...

  3. Takeoff and Landing Performance Assessment - Wikipedia

    en.wikipedia.org/wiki/Takeoff_and_Landing...

    TALPA assessment generates a Runway Condition Code (RWYCC) ranging from 6 to 0, where 6 indicates a dry runway and 0 signifies nil conditions, meaning braking action is minimal to non-existent. Separate runway condition codes are published for each third of a runway, and pilots use a Runway Condition Assessment Matrix (RCAM) to calculate their ...

  4. 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.

  5. Simplified directional facility - Wikipedia

    en.wikipedia.org/wiki/Simplified_directional...

    Morristown Regional Airport's SDF approach procedure to runway 5 before its decommissioning. Simplified directional facility (SDF) was a localizer-based instrument non-precision approach to an airport, which provided final approach course similar to instrument landing system (ILS) and localizer type directional aid (LDA) approaches, although not as precise.

  6. 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.

  7. ARINC 424 - Wikipedia

    en.wikipedia.org/wiki/ARINC_424

    Since its initial publication in May 1975 [4] ARINC 424 has been amended many times, introducing new record types and field values and revised coding rules as required by new technologies and classes of equipment such as GPS and Flight Management Computers. Each amendment is issued as a supplement, a format number suffix indicating the revision ...

  8. Aeronautical chart conventions (United States) - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart...

    White space around the chart is filled with map information and the legend, scales, and tables of airport and airspace information. Terrain is color-coded for its elevation and major roads, cities, and bodies of water are shown for visual reference, as well as other identifiable structures (e.g., stadiums and water towers ).

  9. Displaced threshold - Wikipedia

    en.wikipedia.org/wiki/Displaced_threshold

    Runway 29L at Indira Gandhi International Airport, in Delhi, India, has a displaced threshold of 1,460 m (4,790 ft) from the physical beginning of the pavement. [4] This produces a 1.5 km portion of runway that cannot be used for landing in this direction. This, in turn decreases the available landing length on runway 29L to 2,970 m (9,744 ft).
