What it measures
How far an aircraft has progressed through the FAA's 5-stage type-certification process — the real finish line before US passenger service. Joby completed Stage 4 in 2026; Stage 5 is the certificate itself. (China's EHang is already certified via a separate regulator for its autonomous model.)
