  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 ...

    en.wikipedia.org/wiki/Flight-time_equivalent_dose

    The flight-time equivalent dose concept is the creation of Ulf Stahmer, a Canadian professional engineer working in the field of radioactive materials transport. It was first presented in the poster session [1] at the 18th International Symposium of the Packaging and Transport of Radioactive Materials (PATRAM) held in Kobe, Hyogo, Japan where the poster received an Aoki Award for distinguished ...

    They are defined in terms of V REF of a given aircraft, or if V REF is not specified, 1.3 V s0 at the maximum certificated landing weight. The values of V REF , V S0 , and the maximum certificated landing weight are established for the aircraft by the certification authority of the country of registry.

    The NASA 737 research aircraft on the Wallops runway in 1987 with the microwave landing system equipment in the foreground. The microwave landing system (MLS) is an all-weather, precision radio guidance system intended to be installed at large airports to assist aircraft in landing, including 'blind landings'. [1]

  9. 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.
