Airport Runway Approach Lights

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.

Airport runway approach lights.

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. 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. 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. Use the approach visual approach path and runway lights at your airport and you ll stay on glide and clear of obstructions all the way to the touchdown.

The malsr consisting of a combination of threshold lamps steady burning light bars and flashers provides. Using runway lights to make your flight safer. 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. 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.

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

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