Airfield Ground Lighting

Northlane Solutions supplies and installs runway edge lights, threshold lights, taxiway lighting, PAPI systems, approach lighting and airfield guidance signs for Saudi airports and airfields, engineered to ICAO Annex 14 Volume I and FAA AC 150/5340-30 with photometrics and layout matched to the runway category and approach type of each site.

A runway at night is read entirely through its lighting. A pilot on approach has no other reference for the runway edge, the threshold, or the point where the surface ends, so the layout, color coding and intensity of every fitting is fixed by international standard rather than by preference, and a system built outside that standard is not a lesser version of the real thing, it is unsafe.

What the system covers

Runway edge lighting marks the lateral limits of the usable surface in white, switching to yellow on the final section of runways of 2,400 metres or more to warn of the approaching end. Threshold and runway end lights mark where the runway begins and ends in green and red respectively, visible from opposite directions so a pilot always reads the correct one. Taxiway lighting, typically blue edge lights with green centreline lighting on more complex layouts, guides aircraft on the ground once they have left the runway. PAPI, the precision approach path indicator, gives a pilot a visual glide slope reference on final approach through a bar of lights that reads red, white or a combination depending on whether the aircraft is above, on, or below the correct path. Approach lighting systems extend that guidance further out from the threshold for lower visibility operations, and airfield guidance signs identify taxiway intersections, runway holding positions and mandatory instructions so ground movement stays unambiguous even at night or in reduced visibility.

Standards and specification

Northlane Solutions engineers every airfield ground lighting package to ICAO Annex 14 Volume I and, where the design reference is American, FAA AC 150/5340-30, matching fitting photometrics, spacing and color to the runway category, approach type and the specific configuration of the airfield rather than applying one generic layout. The correct configuration depends on runway length, the approach category it is certified for, and whether operations are expected at night or in low visibility, and NLS works from the aerodrome's own certification basis rather than a default assumption.

Delivery

NLS supplies fittings from established international aviation lighting manufacturers and carries the project from layout design through supply, installation and commissioning, then into the control and monitoring systems, series circuits and cabling that keep the lighting operating as one coordinated system rather than a set of independent fixtures. Maintenance and photometric retesting follow once the system is commissioned, so performance is verified against the standard on an ongoing basis rather than assumed from the installation date.

Runway Edge Lights

Runway edge lights are the fixed white fixtures spaced along both sides of a runway that define its usable width at night or in low visibility, switching to yellow along the final section approaching the runway end on longer runways. Northlane Solutions supplies runway edge light fixtures engineered to ICAO Annex 14 Volume I, elevated and in-pavement, across Saudi Arabia.

Threshold & Runway End Lights

Threshold and runway end lights mark where the landing surface begins and ends, showing green to an approaching aircraft and red to one departing off the far end. Northlane Solutions supplies threshold and end light fixtures, wing-bar arrays, and associated circuit components engineered to ICAO Annex 14 Volume I, for airfield and heliport projects across Saudi Arabia.

Taxiway Lighting

Taxiway lighting, blue edge lights and green centreline lights, guides an aircraft between the runway and apron on the ground at night or in low visibility. Northlane Solutions supplies taxiway edge and centreline fixtures built to ICAO Annex 14 Volume I, including elevated and in-pavement centreline options, as turnkey supply and installation for airfield and heliport projects across Saudi Arabia.

PAPI Systems

A PAPI, precision approach path indicator, is a row of ground units beside the runway that shows a pilot on final approach whether the aircraft sits above, on, or below the correct glide path through red and white lights. Northlane Solutions supplies PAPI systems built to ICAO Annex 14 Volume I for runway and heliport approaches across Saudi Arabia.

Approach Lighting Systems

An approach lighting system extends a defined pattern of light bars, and on longer configurations sequenced flashing lights, outward from the runway threshold along the extended centreline, giving a pilot on final approach horizontal guidance before the runway itself becomes visible. Northlane Solutions supplies approach lighting sized to the runway's approach category, engineered to ICAO Annex 14 Volume I.

Airfield Guidance Signs

Airfield guidance signs, illuminated mandatory instruction, location, and direction signs placed along runways and taxiways, tell a pilot where they are and what boundary or intersection lies ahead, backing up ground lighting and radio instructions with a fixed visual reference. Northlane Solutions supplies illuminated airfield signage engineered to ICAO Annex 14 Volume I sizing and legend requirements across Saudi Arabia.

Frequently Asked Questions

What standard governs runway lighting color and spacing?+

ICAO Annex 14 Volume I, and FAA AC 150/5340-30 where the design reference is American. Both set the color coding, intensity and spacing for edge, threshold, and taxiway lighting according to runway category and approach type.

What does a PAPI system actually show a pilot?+

A bar of lights that reads as red, white or a mix depending on whether the aircraft is above, on, or below the correct glide path on final approach, giving continuous visual glide slope guidance.

Why does runway edge lighting change from white to yellow near the end?+

On runways of 2,400 metres or more, the final section switches to yellow to warn a pilot on take off or landing roll that the runway end is approaching, well before it becomes visible.

Can Northlane Solutions retrofit lighting on an existing airfield?+

Yes. NLS assesses the existing layout against the aerodrome's current certification basis and supplies and installs replacement or upgraded fittings, cabling and control equipment to bring the system into line with the applicable standard.
