Abstract:

The report describes tests and experimentation with intensity control of condenser discharge lights Flashers with a three-step intensity control, and used in a Runway Alignment Indicator Light RAIL System as part of a Medium Intensity Approach Light System with sequenced flashers MALSR during both day and night and over a wide range of visibility conditions. Also, test and experimentation were conducted with a voltage sensing circuit intended to operate the intensity controlled MALSR from the Control Tower using current changes in the runway lighting circuit.
