No 1 AIDU’s charts were held as individual files, each maintained separately by a data maintenance team. The charts overlapped one another meaning one change to the source data could impact multiple charts, causing duplication of effort and inconsistencies. They therefore needed a system that could produce and maintain a variety of digital and paper products, using a single main data store. This would enable them to update their information at time of receipt and in advance of the need for publication.


We worked with No 1 AIDU to develop an Aeronautical Production System (APS). The foundation of the APS is the Aeronautical Object Oriented Database (AOODB) with a schema based on the Digital Aeronautical Flight Information File (DAFIF) specification. In order to amend the data, a custom Graphical User Interface (GUI) and application was also built.


The APS has enabled No 1 AIDU to improve the quality and consistency of their data by maintaining it in a single, central database, rather than numerous individual charts. Alongside the increased productivity, No 1 AIDU is also benefiting from substantial time and cost savings.

No 1 AIDU feeds forces with accurate aeronautical information

“1Spatial has a good understanding of what’s required and over the last couple of years we’ve developed a very collaborative relationship. It’s helped us massively. Not only does it save us a lot of time and money, but it means we end up with the best solution for our needs.”
