RAF Ascension Island

RAF Ascension Island (FHAW) is a medium airport in Cat Hill, St. Helena. Pilots and dispatchers reference it by ICAO code FHAW or IATA code ASI. It sits in Africa.

RAF Ascension Island is a regional commercial airport that doubles as a busy private-aviation base. Operators benefit from full instrument approaches and an FBO infrastructure scaled for regular jet traffic, often without the congestion of the nearest major hub.

The longest runway measures 10,019 ft (3,054 m), a ultra-long-range-class field. Representative aircraft that operate comfortably here include the Gulfstream G650, Bombardier Global 7500, and Dassault Falcon 8X. In practice this transcontinental and transoceanic operations without performance penalties.

RAF Ascension Island sits near sea level at 278 ft.

Local operations run on Atlantic/St_Helena. Scheduled airline service is light enough that it rarely interferes with charter movements, though planners should still expect to coordinate with the handling agent for international turnarounds.
