Airport Runway Approach Lights

Approach lights navigation aids.

Airport runway approach lights.

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. 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. 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. They consist of two rows of transverse light bars symmetrically placed across the runway centerline.

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. Touchdown zone lights are installed on some precision approach runways to indicate the touchdown zone when landing in reduced visibility conditions. The malsr medium intensity approach lighting system with runway alignment indicator lights is a medium approach intensity lighting system als installed in airport runway approach zones along the extended centerline of the runway. Flying at night is difficult however understanding the runway lighting system for your airport is a key to staying safe.

Be sure to check notams to ensure that the lighting system is operational because inoperative lighting systems may require higher instrument approach minimums.

These lights may be visible from up to 8 kilometres 5 0 mi during the day and up to 32 kilometres 20 mi or more at night. 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.
