Solution Obstruction Watch
Cignus has launched Obstruction Watch at obstructions.cignus.ai, monitoring FAA obstruction activity around the airports and radar sites you care about.
It brings OE/AAA filings, the Digital Obstacle File, and obstruction NOTAMs onto one map, tests each case against Part 77 and TERPS surfaces, and alerts on new filings, determinations, and expiries in your watch areas.
"The information about what is going up near an airport has always existed — it just arrives through different FAA channels, on different clocks. Obstruction Watch puts it on one map, against the surfaces that matter, so airports and radar owners hear about a new structure when it is filed, not after it is built." — Florian Hafner, PhD, Chief Technology Officer, Cignus
