Inset and Pole - Mounted Approach Lighting System Sequence Flashers
The subject report was to determine the suitability of two types of sequence flashers, pole-mounted and inset, to operate in an approach zone incorporating either inset lighting or above ground lighting. The work involved: (1) laboratory photometric measurements; and (2) analysis of pilot's response to test flying the light systems. The results of the tests indicate that with minor modification the units may be used in the field.
