Federal Aviation Administration (FAA) Airport Technology Research and Development Branch (ATR) personnel conducted a performance assessment of the Terma X-band Obstruction Light Control (OLC) System. The purpose of this assessment was to determine if the Terma OLC system meets the aircraft detection lighting system requirements specified in FAA Advisory Circular (AC) 70/7460-1L, “Obstruction Marking and Lighting,” Chapter 14 Aircraft Detection Lighting Systems.

FAA ATR personnel assessed the Terma OLC at the Tehachapi Wind Resource Area, located near Mojave, California. This performance assessment, consisting of demonstrations, flight testing, and data analysis was conducted on April 15, 2015. In the performance assessment, a series of flight patterns were flown against the Terma OLC system to demonstrate whether it could meet the FAA performance requirements specified in AC 70/7460-1L. The Terma OLC system performed according to the manufacturer’s specifications and met the performance requirements identified in AC 70/7460-1L.
