This ARP is intended to cover the warning, caution and advisory indicating system required for commercial and military aerospace vehicles. The purpose of this ARP is to recommend certain basic considerations which the design engineer should observe when designing a visual warning indicating system. It is recognized that many types of warning indicators and systems are available for the designer to use. This ARP does not recommend any specific system but outlines design and installation requirements.
One of the referenced documents CFR 25.1322 has dramatically changed and we need to provide guidance on the revision.
