Predicting Photometric Degradation of Exterior Aircraft Lights
ARP6621
This Aerospace Recommended Practice provides guidance for designers and specifiers of aircraft exterior lighting. Typical causes of light degradation and methods of predicting performance degradation in the aircraft environment are given. Although the document considers only exterior lighting, many of the principles and methods discussed apply to interior or flight deck lighting as well.
Rationale:
This document provides guidance in predicting light output degradation of exterior aircraft lighting so that designers can predict the usable life of aircraft lights and ensure that they meet specified performance levels throughout their lifetime.
