Aviation research, sourced & cited.
Curated index of aviation-relevant research from NASA NTRS, NTSB safety studies, FAA CAMI, and academic sources. Every record links back to its original — we don't host PDFs, we describe each paper and credit the authors. Built for cross-link with the rest of Atlas: search by topic, drill into a CFR section or airframe and see the research that bears on it.
