This SAE Aerospace Standard (AS) establishes minimum performance standards for new equipment position lights for nighttime operation. It is intended to describe suitable means for compliance with current Federal Aviation Regulations defining minimum position light requirements. This Aerospace Standard defines minimum light intensity in terms of candelas in vertical and horizontal directions about the longitudinal, vertical, and lateral axes of the aircraft. It also defines color tolerances in terms of limiting chromaticities for the light emitted from the position lights. It is not intended that this standard require the use of any particular light source such as quartz-halogen, incandescent, or any other specific design of lamp.
