  2. Landing lights - Wikipedia

    en.wikipedia.org/wiki/Landing_lights

    Landing lights are usually of very high intensity, because of the considerable distance that may separate an aircraft from terrain or obstacles. The landing lights of large aircraft can easily be seen by other aircraft over 100 miles away. Key considerations of landing light design include intensity, reliability, weight, and power consumption.

  3. Precision approach path indicator - Wikipedia

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

    The PAPI can be seen to the right (non-standard) side of the runway. The aircraft is slightly below the glideslope. 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.

  4. Optical landing system - Wikipedia

    en.wikipedia.org/wiki/Optical_landing_system

    When the wave-off lights are lit, all other lamps are extinguished. The wave-off lights are operated manually by the LSO. Some (particularly later) optical landing systems include additional lamps: Cut lights – Green lamps used to signal different things based on where the approaching aircraft is in its approach. Named for its original use in ...

    Approach lights at Jyväskylä Airport, Finland The approach lighting system of Bremen Airport Approach lighting at Love Field, Dallas. An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end.

  6. Visual approach slope indicator - Wikipedia

    en.wikipedia.org/wiki/Visual_approach_slope...

    Each light is designed so that it appears as either white or red, depending on the angle at which it is viewed. When the pilot is approaching the lights at the proper angle, meaning the pilot is on the glide slope, the first set of lights appears white and the second set appears red. When both sets appear white, the aircraft is too high, and ...

    [23] [59] This usually takes the form of one green light on the dashboard on cars from the 1950s or older, or two green indicator lights on cars from the 1960s to the present, and a rhythmic ticking sound generated electromechanically or electronically by the flasher. It is also required that the vehicle operator be alerted by much faster- or ...

  8. 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.

    For example, a PAR16 lamp is approximately 2 inches or 50.8 mm in diameter. [1] The size of rectangular PAR lamps is expressed as the letters REC followed by the reflector's mouth height, the letter "X", and the reflector's mouth width—with both dimensions in millimeters. For example, REC142X200 lamps are 142 high and 200 mm wide. [2] [3]
