Sign designs and references

• The Federal Aviation Administration’s Advisory Circular 150/5340-18, Standards for Airport Sign Systems, the source for what each kind of airfield sign means, how it’s colored and how panels are ordered into arrays — and AC 150/5345-44, Specification for Runway and Taxiway Signs, for the sign sizes and legend heights.
• The FAA Aeronautical Information Manual, Chapter 2, Section 3 (Airport Marking Aids and Signs), whose plain-language descriptions of each sign shaped the explanations on this site.
• Signs on this site are for design, training, simulation and display. They are drawn from the published standards, not from manufacturer drawings, and aren’t certified for installation on any airfield.

Lettering

Legends are set in the Federal Highway Administration’s Standard Alphabets for Highway Signs (Series D), the same public letterforms Road-Signs.work uses — a close stand-in for the airfield sign alphabet.

Weathered and rusty finishes

The idea for offering signs in different states of wear — a clean, brand-new sign by default, or a weathered or rusty one — came from the US Road Sign Generator on Superhive Market, whose clean, weathered and rusty material options inspired the Weathering and Rust sliders in our sign builder. Our version is drawn independently, as procedural SVG filters, so every finished sign is still a single vector file. Thank you for the idea.
