This SAE Aerospace Standard (AS) establishes minimum performance standards for new equipment position lights. 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.
This document establishes minimum performance levels for aircraft position lights including chromaticity, and light intensity in support of TSO and system certification. Information contained herein has been expanded from AS8037A in the areas of measurement conditions, lumen maintenance, and the inclusion of specific information relative to the use of Light Emitting Diode source technology. It provides minimum requirements for night operation not addressed in CFR Title 14. Position lights shall be capable of daytime operation as well. FAR references have been revised for clarity and test laboratory temperature range has been reduced for accuracy.
