What BVLOS means

Beyond visual line of sight (BVLOS) operations are flights where the pilot can no longer keep the drone in direct, unaided sight. This unlocks powerful applications such as long-range inspection, surveying and delivery, but it removes the most basic safety net in drone flying — the pilot's own eyes. As a result, BVLOS is among the most advanced and tightly regulated areas of UK drone operation.

Why BVLOS is treated as high-risk

Without direct sight of the aircraft, the pilot relies on technology and procedures to detect and avoid other airspace users and hazards. The Civil Aviation Authority (CAA) therefore requires BVLOS operations to be carefully justified through a detailed safety case. These flights fall firmly within the Specific category and need a tailored operational authorisation; they are not permitted under the Open category.

The training and qualification route

There is no single BVLOS certificate that on its own permits these flights. Instead, pilots usually build capability in stages:

• Foundation: The General VLOS Certificate (GVC) establishes core Specific category competence and is taken through a Recognised Assessment Entity (RAE).
• Specialised training: Additional training addresses the particular skills and procedures BVLOS demands, such as managing detect-and-avoid systems and contingency procedures.
• Authorisation: A specific operational authorisation from the CAA, supported by a robust safety case, is required before flying BVLOS.

What a BVLOS safety case involves

Because the risk is higher, the documentation is more demanding. A BVLOS safety case typically addresses:

• How other airspace users will be detected and avoided
• The reliability of the drone and its systems
• Contingency and emergency procedures
• The operating area and how risk to people on the ground is managed
• Crew roles, training and competence

The role of technology and infrastructure

BVLOS often depends on technology such as detect-and-avoid systems, reliable command-and-control links and, in some cases, coordination with other airspace users. The maturity of these systems and any supporting frameworks influences what authorisations are realistically achievable. This is a fast-evolving area, so requirements and possibilities continue to develop.

Who pursues BVLOS

BVLOS is generally pursued by experienced operators and organisations with specific commercial or operational needs, rather than by newcomers. Building a strong track record of safe Specific category operations first puts a pilot or organisation in a much stronger position when seeking a BVLOS authorisation.

Planning a realistic path

• Gain solid experience and a GVC before considering BVLOS.
• Understand that authorisation depends on a thorough safety case, not just training.
• Choose specialised training from CAA-recognised RAEs where available.
• Allow time and resources for the authorisation process.

BVLOS represents the advanced end of UK drone operations. Treat it as a journey that builds on solid foundations rather than a single course, and ensure any formal qualifications come from CAA-recognised providers.
