ALSF-2 / SSALR
Dual Mode High Intensity Approach Lighting System with Sequenced Flashers
The ALSF-2 is an approach lighting system (ALS), which provides the basic means to transition from instrument flight to visual flight for landing on Category II and Category III runways.
The SSALR is an alternate configuration or Simplified Short Approach Lighting System with Runway Alignment Indicator Lights.
The Next Iteration of High Intensity Approach Lighting Systems
NBP’s ALSF-2 / SSALR system is a Dual Mode High Intensity Approach System that provides visual information on runway alignment, height perception, roll guidance, and horizontal references for Category II/III instrument approaches.
NBP’s design allows the system to be easily configured for a full 3,000-foot lighting pattern (in compliance with the requirements of glide slope angle restrictions) or in the shorter 2,400-foot lighting pattern.
A typical system consists of 247 steady burning lights: including green threshold lights (49 lights), red side row-bar lamps (9 rows, 54 lamps), and high intensity steady burning white lights (144), plus an additional 15 flashing lights commonly referred to as flashers. The flashers flash in sequence starting with the flasher farthest from the runway and ending with the flasher closer to the runway threshold. The lights are spaced at 100′ intervals from the runway threshold outward to 2400′. Systems include sequenced flashing lights, which appear to the pilot as a ball of light traveling towards the runway at high speed (twice a second) and provide visual guidance for all landing categories.
The Congressional Approach Lighting System Improvement Program (C-ALSIP) implements a variety of different visual guidance lighting systems: High Intensity Approach Lighting System with Sequenced Flashing Lights (ALSF-2) (CAT II/III); Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights (MALSR) (CAT I); Precision Approach Path Indicator Lights (PAPI); Runway End Identifier Lights (REIL); Runway Edge Lights (REL); and Portable Lights for Remote Airfields. Service provided includes both non-precision approaches as well as Category (CAT) I, II, and III service to congressionally mandated sites.
“Thank you also to Transportation Secretary Pete Buttigieg and FAA Administrator Michael Whitaker for their continued recognition of our ongoing need for dependable air service in American Samoa with this use of yearly congressional appropriations for FAA,”

Improved Performance
Easily configurable depending on airport needs
Easily control and Monitor the functions and health of the system, locally or remotely
Eliminate variables with real-time status monitoring and reporting.
Work Smarter, Not Harder
Intelligence by Design
NBP’s ALSF-2 / SSALR system has been updated to include our proprietary Lamp ID Technology. This enables Air Traffic Controllers (ATC), and Technicians to be alerted the moment a bulb is out. What’s more, since each lamp has a unique ID, maintenance techs. know the exact location of any outages.
The system can be either controlled locally, from the substation using the Control & Monitor (CM) Panel, or remotely from the Air traffic Control Tower (ATCT) using the Remote Control Panel (RCP), or from the FAA regional centers via the Remote Monitoring Subsystem (RMS).
Since 1966, NBP has established an undisputed reputation for innovation, quality, performance and integrity in the engineering, design and manufacturing of Landing Visual Aids including Approach Lighting Systems and Monitoring and Control Systems for the aviation, utility and defense industries. NBP also offers training and field support services.
