Portland Heliport, located on the Isle of Portland in Dorset, has been recognised as a CAA CAP3145 approved UAS test site, reinforcing its position as a key location for unmanned aircraft systems (UAS) testing and evaluation in the UK. This approval highlights the Heliport’s capability to support structured drone testing activities within a controlled aviation environment.
CAP3145 is a UK Civil Aviation Authority (CAA) framework that defines the requirements for recognised UAS test sites. Approval under CAP3145 demonstrates that a facility can support drone testing, evaluation and development activities in accordance with established aviation safety and operational standards. Operating within such an environment allows organisations to undertake testing programmes with greater confidence, particularly when progressing towards regulatory approvals, including SORA (Specific Operations Risk Assessment) and BVLOS operations.
Portland Heliport offers a unique combination of aviation infrastructure and geographic advantages, making it ideally suited for drone testing in the UK. As a CAA-licensed heliport with access to coastal airspace, Portland Harbour and adjacent coordinated Danger Areas, the site provides a flexible environment for a wide range of UAS operations. From early-stage system trials through to advanced flight testing and operational validation, the facility enables organisations to develop and refine their platforms within a managed and safety-focused setting.
As a CAP3145 approved UAS test site, Portland Heliport plays an important role in supporting the development and certification of unmanned aircraft systems in the UK. The site enables organisations to carry out structured testing and evaluation activities that contribute towards demonstrating safety, performance and operational capability. This is particularly relevant for companies working towards commercial deployment, regulatory approval or integration into complex airspace environments.
The ability to test in a realistic operational environment is critical for advancing UAS capabilities. Portland Heliport provides access to both land-based and maritime environments, allowing organisations to simulate real-world mission scenarios such as logistics, inspection, surveillance and offshore operations. By combining aviation infrastructure with operational flexibility, the site supports the continued growth of drone technology across commercial, industrial and defence sectors.
