Airport Runway Approach Lights

On runways with both approach lighting and runway lighting runway edge lights taxiway lights etc systems the approach lighting system takes precedence for air to ground radio control over the runway lighting system which is set at a predetermined intensity step based on expected visibility conditions.

Airport runway approach lights.

Since our first day of business in 1967 for the past 50 years we ve become a trusted source for airport lights lamps lenses papi runway signage and electrical supplies. They consist of two rows of transverse light bars symmetrically placed across the runway centerline. An approach lighting system or 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. On runways with both approach lighting and runway lighting runway edge lights taxiway lights etc systems the approach lighting system takes precedence for air to ground radio control over the runway lighting system which is set at a predetermined intensity step based on expected visibility conditions.

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 approach. Flying at night is difficult however understanding the runway lighting system for your airport is a key to staying safe. Using runway lights to make your flight safer. Touchdown zone lights are installed on some precision approach runways to indicate the touchdown zone when landing in reduced visibility conditions.

The airport facilities directory a fd and instrument approach charts identify the type of runway lighting available for each runway and how to activate the lighting system. Be sure to check notams to ensure that the lighting system is operational because inoperative lighting systems may require higher instrument approach minimums. Approach lights navigation aids. Als usually serves a runway that has an instrument approach procedure iap associated with it and allows the pilot to visually identify the runway environment.
