FTB 600 High Intensity Wave-Off Beacon

Helideck Status Light System
Categories: ,

The FTB 600 class beacons provide ultra-high intensity wave-off signals for visual indication to abort a landing. The beacon can be activated manually or by an automatic runway incursion system. In addition to providing an “imminent danger” warning when verbal communications are difficult, they may also be used for non-scheduled runway closures.


Originally designed for the U.S. Navy and used for many years as an abort (wave-off) signal for Navy pilots, they were also employed by NASA for Space Shuttle landing sites. The FTB 600 series is now available for commercial use.
