Airfield Lighting

An elevated unidirectional halogen unit, left of the runway, showing an aircraft on final whether it is high or low on the glide path by its white-to-red ratio — more white when high, more red when low. The optics keep the red/white transition line straight, so the crew reads a clean boundary; coated filters hold a firm, heat-stable coating that does not fade under halogen heat. A four-digit display reads elevation; operation and calibration-flight modes mean aiming and flight checks need no external instrument.

A 12-inch unidirectional in-pavement fixture designed specifically for precision approach lighting systems, usable as an approach centerline light or as a crossbar light, giving aircraft clear, dependable visual guidance during approach and landing at night and in low visibility. Used as an approach centerline light, the fixtures are set along the extended runway centerline and indicate the direction of the runway center with a continuous, conspicuous light signal, helping pilots establish and hold the approach path accurately. Used as a crossbar light, the fixtures are set perpendicular to the approach centerline and form a distinct lateral light marking that gives pilots a direct position and distance reference, helps them judge where the aircraft is relative to the runway centerline and the runway threshold, and improves visual recognition during the approach. The fixture uses a unidirectional light distribution, and its photometric performance meets the relevant requirements of ICAO Annex 14, Volume I, providing steady, clear and readily identifiable light guidance throughout the precision approach; it is used in airport runway approach lighting systems.

An LED sequenced flashing light system, elevated or inset, for CAT I, II and III approach lighting; the fixtures fire from the outer end toward the threshold, drawing the approach direction as a moving band of light. Unit control sits inside each fixture, so no separate cabinet is needed, with fewer terminations to inspect. Against xenon flashers, LED units draw less power at a higher power factor, easing load and disturbance on the supply circuit, while an integrated constant-current driver holds flash intensity steady.

An elevated unidirectional LED unit, grouped left of the runway, marking the glide path by its white-to-red ratio — more white high, more red low. The optics keep the red/white transition band narrow and the boundary straight, so height reads off a line, not a color spread. Elevation, mode and fault codes read through the front glass without opening it, so inspection disturbs neither seal nor aim. The units link by CAN, and the group shuts down on a fault rather than show wrong guidance.

Approach centerline lights are used in the airport approach lighting system, set along the extended runway centerline or in crossbar positions to give aircraft clear approach direction and position guidance at night and in low visibility. The continuous, conspicuous light signal helps pilots establish and hold the correct approach path and identify the runway threshold and the direction of the centerline, improving visual judgment during the final approach. The fixture uses an LED light source and a light distribution designed for the application; its photometric performance is aligned with the requirements of the corresponding airfield lighting system, giving airport operations a steady, clear and easily identified visual signal.

Approach side row lights are used in the side rows of a precision approach lighting system, normally set on both sides of the approach centerline to establish a clear lateral position reference for the aircraft. They work with the approach centerline and crossbar lights to help pilots judge where the aircraft is relative to the runway centerline, and they strengthen recognition of the approach lighting pattern in low visibility.

A white sequenced flashing light system, elevated or inset, set along the approach lighting centerline: the fixtures fire from the outer end toward the threshold, so the inbound course reads as a band of light rolling toward the runway. Low-voltage flashtubes keep the system at a modest working voltage, which limits electrical risk during servicing; self-aligning optics let a flashtube or lens be replaced without re-aiming. Each fixture has its own control cabinet with an independent CPU, so one failure cannot stop the system.

Approach lights, both centerline and crossbar, are used in the airport approach lighting system, set along the extended runway centerline or in crossbar positions to give aircraft clear approach direction and position guidance at night and in low visibility.
