Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights (MALSR)

MALSR System

MALSR (Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights) is used by pilots during instrument landing approach to align the aircraft with the centerline of the runway. Up to sixty-three (63) steady-burning lights are used to create a reference plane, and up to eight (8) lights create a sequential strobing flash pattern that rolls toward the runway threshold. Three intensity settings allow the approach to be used under changing weather conditions. MALS (Medium Intensity Approach Lighting System) is available. A 6.6a series circuit powers the entire MALSR system. This provides for greater dependability, increased control, decreased maintenance, improved efficiency and lower installation costs.


MALSR Components:

FAA L850E ZA485
Threshold Fixtures
Green lights that mark the beginning of the runway and may be semiflush FAA L850E (ZA480, 210w) or elevated FAA E982 (ZA420, 100w*).
* Exceeds 150 PAR/SP photometrics.


FAA E982 ZA420
Steady-burn Lights
White lights that form a reference plane to aid in aircraft alignment with the runway and may be semiflush FAA E2491 (ZA480, [email protected]) or elevated FAA E982 (ZA420, 150w*).
* Exceeds 150 PAR/SP photometrics.


Sequence Flasher Fixtures
Sequence Flasher Fixtures
White lights that create a sequential strobing flash pattern that rolls toward the runway threshold. May be mounted on frangible masts or frangible couplings. FAA L849, Style A and E (FTS 815 voltage-powered, FTS 835 current-driven).


Fiberglass Frangible Approach Mast
Fiberglass Frangible Approach Mast
These low impact resistant (LIR) support structures are available in 6 ft to 128 ft heights to provide a high intensity guidance system in the clear zone. They are the only masts that are fully compliant with FAA-E2702 specs.


Constant Current Regulator
Constant Current Regulator
A single 6.6a L828, 15kw saturable reactor regulator can power the entire MALSR system. All lights will have the required three intensity settings.


Series Isolating Transformer
Series Isolating Transformer
FAA L830 rubber encapsulated series isolating transformers are waterproof for above ground, pull pit or ground burial installation.


L823 Connector Kits
L823 Connector Kits
Primary and secondary connector kits provide strong waterproof connections between components.
