AIRBORNE SECURITY HOW DO WE COPE?

摘要

In accordance with the ICAO standards, tall structures in the UK are promulgated within the Aeronautical Information Publication (AIP) En Route Section (ENR) at 5.4 (Air Navigation Obstacles-En-Route). Significantly, the AIP ENR section only lists structures that have a height of 300 ft/91.4 m. agl or more. Further, such structures are then charted on the UK 1:500,000 and 1:250,000 series VFR charts produced by NATS on behalf of the CAA.This means that in the UK, unless detailed within Aerodrome Section of the AIP, structures of a height of less than 300 ft. agl will not routinely be promulgated for civil aviation purposes. It follows that uncharted structures, some as high as 299 ft. agl, could be encountered anywhere in the UK FIRs.
