Navigation restrictions that are applicable to unmanned aircraft systems are published in the UK AIP (Section ENR 5.1 Prohibited, Restricted and Danger Areas) including restrictions applicable around aerodromes (Flight Restriction Zones) and restrictions applicable around other areas. Datasets of all ENR 5.1 airspace restrictions applicable to UAS have been created to allow end users the ability to view the data in separate viewers (Free AIXM Viewers) or integrate with other applications. The datasets provided as digital files will be delivered in line with the AIRAC Effective Date of the UK AIP AIRAC cycles and will remain effective until replaced.
