Evaluate Improved Airport Beacon
Two forms of experimental beacons, strobe and incandescent, were tested to determine their suitability as improved replacement for the standard 36-inch rotating airport beacon presently in use. Neither unit demonstrated a clear cut superiority over the standard beacon, and the need for further development effort was indicated. A type of low-cost incandescent airport beacon was evaluated at the same time and found suitable for use at smaller, secondary airports.
