Yaoundé Nsimalen International Airport NSI / FKYS

Verified Sep 2026: coordinates 3.7225N/11.5533E, elevation 694m/2278ft, and runway 01/19 (3400m x 45m asphalt, no ILS) all confirmed exactly as drafted against independent sources. Website corrected — the legacy domain adcsa.aero now issues a 302 redirect to adcsa.info; contact email still resolves on the old adcsa.aero domain so was left unchanged. Runway 01/19 carries no ILS — approaches reportedly rely on VOR/DME (NLY 115.70) and NDB (YNS 368) only, non-precision (retained from draft, not independently reverified against a primary AIP chart). ADC operates seven airports total — Yaoundé-Nsimalen, Douala, Maroua-Salak, Garoua, Ngaoundéré, Bertoua and Bamenda — confirming the draft's Douala-plus-five-other claim; this remains Camair-Co's home hub and Cameroon's second-busiest airport after Douala. Ownership breakdown corrected above — the draft's 63/20/8 percent split naming ASECNA and Camair-Co as shareholders conflicts with the most recent published ADC shareholding data located (91% state / 9% institutional investors, dated 2016); neither figure could be confirmed against a primary ADC filing, so this should be rechecked. The 560,000 (2024) pax figure remains an unverified estimate — only older published figures were found (190,487 in 2004; 208,973 in 2009), so no current total could be corroborated either way. ICAO Class A aerodrome certification (2022) and the Feb 2024 ASECNA Category 1 operational-status upgrade request are retained from the draft but were not.
