![]() ![]() VGLS is focused on sustaining and supporting Performance Based. Enabling pilots to more effectively identify the runway environment, align with the runway centerline and achieve stable, wings-level attitude for landing. New foundations, LIR structures were installed and tied into STA 22. Visual Guidance Lighting Systems (VGLS) provides visual guidance to pilots during the approach and landing phases of flight. STA 23 and 24 of the ALSF were relocated to accommodate the new end around taxiway. Once the systems were running on the new fiber and comm, the old comm structure was demolished.ĭACO tested and terminated all comm wire. (ALSF-2) for use on category II and category III precision-instrument. ALSF-1 systems will typically be located at runways with only CAT I approach capabilities. A carful cutover plan was completed by DACO which allowed for both comm structures to be utilized and eliminated down time for the ILS systems to a day. These include a high-intensity approach lighting system with sequenced flashing lights. An ALSF-1 system is essentially the same as an ALSF-2 system, but lacks the additional decision bar and red lights after the 1000 decision bar. 2 light bars each with 8 steady burning white. A typical ALSF-II/SSALR system consist of the following light fixture components: 24 light bars each with 5 steady burning white PAR56 fixtures. DACO installed new fiber from the new shelter back to the ATCT and ran new fiber, heliax, 6 pair, 12 pair, 25 pair, 50 pair and 100 pair PE-39 copper shield cable to each affected facility on RW 13L-31R. The ALSF-II/SSALR system usually is a 2400-foot-long array of lights but can be longer or shorter depending on local terrain and requirements. If this shelter was removed, then DFW would lose all of its ILS systems on the east side of the airport. The ALSF-2/SSALR system is a Dual Mode High Intensity Approach Lighting System providing visual approach lighting patterns for landing aircraft on Category II and Category III runways. The existing ILS comm structure housed fiber and copper comm that served the entire east half of DFW. The ALSF-2 is a High Intensity lighting system, so lights used in the system are defined in the FAA order as follows: High Intensity Systems. DACO installed all the electronic and electrical infrastrure in the new shelter to replace the old comm structure. ![]() This new structure housed the fiber and communication electronics that served the ILS. ![]() Pricing and Availability on millions of electronic components from. A new ILS support structure was attached to the existing ALSF shelter by expanding east. WW-ALSF-2-Accessories-Optoelectronics from Interlight. DACO was hired to relocate the ALSF shelter and light lane stations as well has re-cable all of the existing ILS infrastrucres serving both parallel runways with new fiber and copper control wire. The RMS includes a remote Maintenance Processor Subsystem (MPS) interface.Dallas Fort Worth International Airport required an ALSF shelter and light lane be modified as part of their end around project. NAS, and support CAT II and III operations. The NBP ALSF-2/SSALR system includes a Remote Monitoring Subsystem (RMS) that monitors the system status and provides diagnostic capabilities for the entire system. ALSF-2 lights represent the most complex and expensive ALS in the U.S. Note: ALSF Approach Lighting with Sequenced Flashing Lights. The system meets all of the lamp monitoring and failure reporting requirements of the latest ALSF-2/SSALR specification FAA-E-2689a Amendment 2.1.1. General aviation traffic is also popular, with two fixed base operators providing a. The mode and intensity of the Sequenced Flashing Lights are automatically selected based on the mode and brightness level of the steady burning approach lights. The steady burning approach lights are configured in five lighting loops controlled by dry-type Constant Current Regulators (CCRs). The system can be controlled locally from the substation using the Control & Monitor (CM) or remotely from the Air Traffic Control Tower (ATCT) using the Remote Control Panel (RCP). The system can be installed in the full 3,000-foot lighting patterns (in compliance with the requirements of glide slope angle restrictions) or in the shorter 2,400-foot lighting patterns. ![]() The system operates in two modes: a High Intensity Approach Lighting System with Sequenced Flashing Lights (ALSF-2), and a Simplified Short Approach Lighting System with Runway Alignment Indicator Lights (SSALR). The ALSF-2/SSALR system is a Dual Mode High Intensity Approach Lighting System providing visual approach lighting patterns for landing aircraft on Category II and Category III runways. ALSF-2 (Approach Lighting System with Sequenced Flashing Lights) is used on Category II runways during instrument landing approach to align the aircraft. ![]()
