The UK Proposed Approach to Common Information Service Provider (CISP) and Discovery and Synchronisation Service (DSS)

Overview

The increasing use of UAS operations across commercial, government, and recreational domains represents a transformative shift in the aviation landscape. This growth brings with it multiple opportunities yet also presents significant challenges. Notably, how to integrate these emerging airspace users safely, efficiently, and at scale into the existing aviation system.

The UK has set out strategic objectives to enable the integration of beyond visual line of sight (BVLOS) Uncrewed Aircraft System (UAS) operations at scale. This document sets out the CAA's consultation on components of a proposed approach to integrating UAS operations into the UK air traffic management (ATM) and air navigation service (ANS) environment, of which Uncrewed Aircraft System Traffic Management (UTM) forms an important part, with a focus on data sharing requirements and the functionalities to enable this. 

The Department for Transport (DfT) asked the CAA to develop and consult on a proposed approach to these requirements and functionalities. This consultation is a necessary step before any policy or legislative changes can be introduced. It provides relevant stakeholders with the opportunity to contribute their views and help shape how the proposed framework could be implemented in practice.

The CAA has developed a provisional approach, which is outlined in this document. Through this consultation, the CAA seeks views on whether the proposed approach is appropriate and how the associated requirements and functionalities can be designed and implemented in a practical, fair and effective manner.

The CAA welcomes evidence regarding the advantages, disadvantages and practical implications of alternative approaches, including their impacts on safety, resilience, competition, scalability, interoperability and affordability.
