UK CAA publishes guide to support BVLOS

The UK Civil Aviation Authority (CAA) has published a guide aimed at supporting the industry to make unmanned aircraft (drone) flights beyond the visual line of sight of the operator (BVLOS) an everyday occurrence. According to the regulator, this would significantly change how unmanned aircraft are used in the UK.

Currently BVLOS flights require permission from the Civil Aviation Authority and can only occur in specific, restricted cases. Normalising BVLOS will continue to push the UK forward as a world-leader in aviation innovation and technology. Allowing BVLOS operations in the UK could bring huge benefits, including:

  • Drone parcel delivery from a distribution centre to a customer
  • Long-distance aerial surveys of infrastructure such as power lines or highway construction
  • Surveillance at the scene of an accident or incident, operated from an external control centre
  • Street mapping a whole city with optical and acoustic sensors

The guide details how future BVLOS operations can be achieved through testing and technology development. They set out the need for the regulator and innovators to build, test, learn and repeat in partnership in small steps to work toward the vision of safe BVLOS operations becoming business as usual in the UK.

David Tait, Acting Head of the CAA’s Innovation Team, said: “Enabling everyday drone flying beyond visual line of sight is a game changer, providing the opportunity for unmanned vehicles to monitor critical infrastructure, make deliveries and support our daily lives in an efficient and environmentally friendly way. We are now working closely with some of the world’s leading innovators to make these amazing possibilities a reality.”

One company involved in the CAA’s innovation work is, a Techstars-backed startup led by four former employees of Arup, Apple, CERN, McLaren and hedge funds. is developing technology that will enable drone service operators to fly drone missions BVLOS, from a central control room, at scale. Initial focus is on closed industrial sites, e.g. construction, infrastructure and oil & gas. Tests are planned with companies such as Skanska, Atkins and the fire service, supported by NATS and Vodafone. John McKenna, CEO of, said: “Under conventional visual line of sight rules, operations have virtually zero economies of scale. In contrast, a centralised BVLOS approach improves on almost every measure with scale – including quality, safety, responsiveness and cost.”

This roadmap has been produced by the CAA’s Innovation Team, initially funded by a Department for Business, Energy and Industrial Strategy (BEIS) grant.
