  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. Transponder landing system - Wikipedia

    en.wikipedia.org/wiki/Transponder_Landing_System

    For an aircraft conducting an instrument approach, the TLS will transmit horizontal and vertical guidance signals to the ILS receiver and cockpit avionics that are identical to those of an ILS. The signals will thus appear to emanate from fixed locations where ILS antennas are typically installed.

  4. Flight instruments - Wikipedia

    en.wikipedia.org/wiki/Flight_instruments

    The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.

  5. 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 ...

  6. Horizontal situation indicator - Wikipedia

    en.wikipedia.org/wiki/Horizontal_situation_indicator

    The horizontal situation indicator (commonly called the HSI) is an aircraft flight instrument normally mounted below the artificial horizon in place of a conventional heading indicator. It combines a heading indicator with a VHF omnidirectional range - instrument landing system (VOR-ILS) display.

  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. SCAT-I - Wikipedia

    en.wikipedia.org/wiki/SCAT-I

    SCAT-I (Special CATegory I) is an instrument landing system for aircraft, based on Differential GPS. It is developed under project management by Avinor , the Norwegian airport administration. It is installed on several short runway airports for domestic operation in Norway.

  9. Marker beacon - Wikipedia

    en.wikipedia.org/wiki/Marker_beacon

    An LOM is a navigation aid used as part of an instrument landing system (ILS) instrument approach for aircraft. Aircraft can navigate directly to the location using the NDB as well as be alerted when they fly over it by the beacon. The LOM is becoming less important now that GPS navigation is well established in the aviation community. [4]
