  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 ...

    It is typically located about 1 NM (1.85 km) inside the point where the glideslope intercepts the intermediate altitude and transmits a 400 Hz tone signal on a low-powered (3 watts), 75 MHz carrier signal. Its antenna is highly directional, and is pointed straight up. The valid signal area is a 2,400 ft (730 m) × 4,200 ft (1,280 m) ellipse (as ...

  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. [1]

  7. Precision approach radar - Wikipedia

    en.wikipedia.org/wiki/Precision_Approach_Radar

    Precision approach radar or PAR is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached. [1] Controllers monitoring the PAR displays observe each aircraft 's position and issue instructions to the pilot that keep the aircraft on course and ...
