The adoption of performance-based regulation further supports innovation by allowing companies to meet safety requirements through diverse compliance strategies rather than rigid rule-based approaches.
Furthermore, the CAA has introduced policies to enable BVLOS flights in Atypical Air Environments (AAE). These are areas with reduced conventional air traffic due to proximity to ground infrastructure, such as operations within 100 feet of structures, 50 feet of linear infrastructure like railways, and confined industrial sites. This policy enhances safety while unlocking BVLOS applications for routine tasks such as powerline inspections, wind turbine maintenance, and site security.
Where UAS BVLOS can fly in the UK today?
In the UK, Beyond Visual Line of Sight (BVLOS) drone operations are primarily conducted within segregated airspace, such as Danger Areas. These zones are designated to ensure separation between unmanned and manned aircraft, allowing BVLOS flights to operate safely. To conduct BVLOS operations in non-segregated airspace, operators must obtain specific authorisations from the Civil Aviation Authority (CAA). This requires demonstrating robust safety measures, including effective Detect and Avoid (DAA) systems and comprehensive risk assessments. The CAA's guidance document, CAP 722, provides detailed information on the regulatory framework and requirements for BVLOS operations in various airspace classifications. The CAA CAP 722 framework from the UK Civil Aviation Authority governs BVLOS operations, ensuring safe airspace integration for future drone advancements.
BVLOS in Atypical Air Environments (AAE)
In October 2024, the Civil Aviation Authority introduced a policy to enable BVLOS flights in Atypical Air Environments (AAE). These are areas with reduced conventional air traffic due to proximity to ground infrastructure. Examples include operations within 100 feet of structures, 50 feet of linear infrastructure such as railways, and confined industrial sites. This policy enhances safety while unlocking BVLOS applications for routine tasks such as powerline inspections, wind turbine maintenance, and site security.
