UK – EU Transition, and UK Civil Aviation Regulations

To access current UK civil aviation regulations, including AMC and GM, CAA regulatory documents, please use this link to UK Regulation. Please note, if you use information and guidance under the Headings, the references to EU regulations or EU websites in our guidance will not be an accurate information or description of your obligations under UK law.

The Known Consignor Scheme is voluntary. There is no legal requirement for any air cargo to be dispatched from the shipper as SPX (Secure) cargo; insecure cargo may still be shipped, although it will be subject to additional security measures before it can be allowed to fly.

On approval, Known Consignors are permitted (provided they comply with the requirements outlined in the regulations) to ship cargo from source. Such cargo may be transported by air without the need for any further security measures being applied.
