For more than 50 years No1 Aeronautical Information Documents Unit (No1 AIDU) has been at the forefront of the Air Cartographic world. Established in 1953 and subsequently relocated to RAF Northolt in 1957, No1 AIDU has recently fallen under the wing of ICG and JAGO, bringing it within the same chain of command as all military agencies, such as DGC and Mil Survey. Thus providing valuable geospatial data to all aspects of HM Armed Forces.

No1. AIDU is charged with the production of all aspects of aeronautical data, including arrival, departure and in-flight data as well as some of the more specialised digital cockpit moving map imagery. With an area of coverage that may be required for training missions, search and rescue sorties, areas in need of humanitarian aid and areas of military operations it is as important as ever that No1 AIDU’s aeronautical data “Rises above the rest”.
