The Honeywell MALSF System is a medium intensity approach lighting system that provides a visual lighting path for landing aircraft.
The MALSF system usually is a 1400-foot-long array of lights but can be longer or shorter depending on local terrain and requirements.
A typical MALSF system consists of the following light fixture components:
• 9 light bars each with 5 steady burning white PAR38 fixtures
• 5 sequence flashing white PAR56 fixtures
• Threshold bar of 18 steady burning green PAR56 fixtures.
The MALSF system can be mounted on 2-inch EMT, up to a 6-feet mounting height or on frangible towers over 6 feet.
System control of the sequence flashing lights is accomplished through the master controller selecting one of three light intensities: low, medium, or high. Both the sequence flashing and the steady burning light systems provide for either local or remote control.
