Abstract : The report summarizes the work performed for the development of an experimental sequences flasher system for use in precision approach lighting systems. The system is designed to be installed in conjunction with an existing steady-burning approach light system requiring no additional wiring. A master timer mounted at the power station superimposes a timing signal on the series power loop of the steady-burning lights. A power supply for each flashing light derives power and timing signals from the series power loop at each station. The system is designed to produce a beam axis effective intensity of between 13000 and 20000 candelas and a minimum effective intensity of 6000 candelas 12 1/2 degrees off the beam axis. These intensity values must be attained when flashed in sequence twice per second. The measured intensities on the delivered units were within the required values. The system flashes the lamps at 1/60 - second intervals, starting with the outermost lamp and progressing toward the runway creating a 'rolling ball' effect. (Author)
