Implementation and Safeguarding of IFPs in the UK

The Air Navigation Order 2016 as amended empowers the CAA to approve IFPs design before their notification in the UK Aeronautical Information Publication (AIP).

IFPs are regulated in the UK through the oversight of Approved Procedure Design Organisations (APDOs) and the approval of IFPs design before their implementation in the UK Aeronautical Information Publication (AIP).

The specific requirements for the development and approval of IFP designs, and the delivery of safeguarding services are published in this publication.

The CAA has published a revised version of CAP 1616, Airspace Change Process, which implements the latest government policy set out in the Air Navigation Directions 2026 and the Air Navigation Guidance 2026. These changes come into effect on 1 October 2026 and this publication will be updated in due course to reflect any relevant changes.
