    en.wikipedia.org/wiki/Glide_path

    Emission patterns of the localizer and glide slope signals Glide slope station for runway 09R at Hannover Airport in Germany. In aviation, instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path ...

  3. Visual Glide Slope Indicator - Wikipedia

    en.wikipedia.org/wiki/Visual_Glide_Slope_Indicator

    Visual Glide Slope Indicator or Visual Glideslope Indicator (VGSI) is a ground device that uses lights to assist a pilot in landing an airplane at an airport.The lights define a vertical approach path during the final approach to a runway and can help the pilot determine if the airplane is too high or too low for an optimum landing.

  4. Optical landing system - Wikipedia

    en.wikipedia.org/wiki/Optical_landing_system

    In its developed form, the OLS consists of a horizontal row of green lights, used as a reference, and a column of vertical lights. The vertical lights signal whether the aircraft is too high, too low, or at the correct altitude as the pilot descends the glide slope towards the carrier's deck. Other lights give various commands and can be used ...

  6. 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 ...

  7. Visual approach slope indicator - Wikipedia

    en.wikipedia.org/.../Visual_approach_slope_indicator

    The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.

  8. Precision approach path indicator - Wikipedia

    en.wikipedia.org/wiki/Precision_Approach_Path...

    A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately 300 metres (980 ft) beyond the landing threshold of the runway.

  9. Final approach - Wikipedia

    A composite image of an Alliance Airlines Fokker 70 on final approach at Christmas Island Airport, illustrating the approach slope to the runway. The term glide slope is sometimes used to mean approach slope, although in precise usage the glide slope is the vertical guidance element of the instrument landing system. [2]
