This document is a Federal Aviation Administration (FAA) Specification for Transparent Plastic Window Shades (FAA-E-2470), dated December 5, 1985, which supersedes previous versions. The specification establishes detailed technical requirements for transparent plastic window shades designed specifically for Airport Traffic Control (ATC) Tower cabs, focusing on material composition, solar optical properties, and installation standards.

Key technical specifications include: shade film must be manufactured from a polyester polymer meeting Federal Specification L-P-377b, constructed with Massachusetts Type SSLW-500-SR/Gray film, laminated with 1.5 mil thick polyester, and protected with a scratch-resistant coating. The shades must have strict solar optical performance requirements, including transmitting no more than 6% of visible solar energy, 4% of ultra-violet solar energy, and rejecting 48% of total solar energy. Additional requirements cover shade components like bottom bars, shade cords, rollers, mounting brackets, and installation procedures, with precise measurements and positioning guidelines for ATC tower environments.
