Service Test of the Pathfinder Beacon Light.

Abstract

Six beacon lights were operated under various meteorological conditions during the hours of dusk (sunset to end evening nautical twilight (EENT)), dawn (begin morning nautical twilight (BMNT) to sunrise), and darkness (EENT to BMNT). The beacons were operated at various heights above the ground using continuous and coded light settings, various color lenses, and shielded light settings. USAAVNTBD personnel observed the beacon lights for approximately 25 flights hours from fixed-wing and rotary-wing aircraft. (Author)
