This document recommends design objectives for navigation, position, and anticollision light systems for visual detection and collision avoidance between aircraft in flight and on the ground. Customers for new aircraft or lighting components and designers or manufacturers may take advantage of this document in specifying the initial requirements that, in most cases, significantly exceed the applicable minimum intensities as shown in the Code of Federal Regulations as well provide better stability, longer life, and lower operating costs.
