Yaoundé Nsimalen International Airport (French: Aéroport international de Yaoundé-Nsimalen) (IATA: NSI, ICAO: FKYS), also known as Nsimalen airport, is the second busiest and largest public airport in Cameroon. The airport is located 27 km (16 miles) south of the capital Yaoundé, near Nsimalen in Cameroon's Centre Province. Nsimalen was built to supersede the old international airport in Yaoundé that was getting absorbed by the rapid growth of the city, it was also too close to the oil deposits of SCDP (Cameroon Oil Company Filings).
