The Avlite LED Medium Intensity Approach Lighting System (MALSR) is engineered to provide pilots with critical visual guidance during instrument landing approaches. It aids in aligning the aircraft with the runway centerline, enhancing height perception, roll guidance, and offering essential horizontal references to ensure safe and precise landings. This system plays a vital role in improving situational awareness, especially under low-visibility conditions.
The MALSR is composed of two primary subsystems that work together to deliver comprehensive visual cues. The first subsystem is the Sequence Flashing Lights (SFL) or Runway Alignment Indicator Lights (RAIL), which consists of five lights flashing in a timed, uniform sequence. This sequential flashing creates a dynamic visual pathway that helps pilots maintain accurate alignment with the runway centerline. The second subsystem is the Steady Burning Array, which includes nine lightweight barrettes, each equipped with five LED light heads, providing continuous steady illumination to assist with height and horizontal positioning during the approach.
Avlite’s advanced LED optics technology used in the AV-MALSR achieves exceptionally low power consumption while maintaining the intensity required to deliver critically accurate approach information. This efficiency allows the system to operate economically in both permanent installations and portable configurations. The system offers flexible power options to suit a wide range of operational needs, including solar stations, generator kits, battery kits, and AC power sources. Control options are similarly versatile, with fixed, wireless, or manual controls available to accommodate different installation and operational preferences.
Configurations of the system have evolved to include MALSF, MALS, SALS, SSALS, SSALSR, and SSALF, reflecting a range of solutions tailored to specific airport or mission requirements. Both folding portable and permanent frangible versions are offered to support commercial and military operations alike. Power sources cover 24 VDC, 100-240 VAC, batteries, and solar energy, providing adaptability for remote or infrastructure-limited locations. Control methods vary from wireless and power line control (available in AC versions) to manual controls, allowing operators to select the best option for their particular application.
The AV-MALSR system is fully compliant with relevant aviation standards, including the FAA’s MALSR requirements, UFC-3 guidelines, and NAVAIR standards for medium intensity approach lighting steady burning arrays. This ensures that it meets stringent regulatory criteria for safety, reliability, and performance, making it suitable for a wide range of civil and military airfield lighting applications.
