Development of 60 Watt Wide Angle Taxiway Light for Short Radius Taxiway Turns

摘要

A design and development program was conducted to produce a 60 Watt Wide Angle Taxiway Light for use in airports along the center line of short radius taxiway turns. The light was designed and tested in accordance with Federal Aviation Agency Specification FAA-ER-430-020. The light is bidirectional and projects a light pattern of 100 candela over a 60 degree horizontal spread and 0 degree to 10 degree vertical spread. The light is inset in the taxiway and has a maximum rise of 3/8 inches above the pavement level with a conical slope of 8 degree maximum. The two parts of the light are the Base and Optical Housing. The Base is permanently installed in the runway with a suitable adhesive. The Optical Housing is a sealed capsule that houses the lens, lamp, and by-pass device and can be easily removed from the base for maintenance or service. Photometric tests indicate this light unit will improve visual guidance for aircraft taxiing on short radius turns.
