ALSF Flasher Systems are used as approach aids. Precision approach to runway in visibility conditions where the runway visual range (RVR), is less than one-half mile requiring steady-burning approach lights with sequence flashing lights. The system consists of a master controller for monitoring and individual flashing lights that can be incorporated with steady burning lights to create various types of approach light systems such as the classic 21-position ALSF-1 or ALSF-2. Flashhead and power converter may be mounted as one unit or individually to meet local terrain needs. Inset (surface mount) flashers are also available. Other parts of the system, such as steady burning lights, towers, light bases, transformers and regulators must be ordered separately.
