BVLOS Drone Operations Overview UK 2026

What Are BVLOS Operations?

Beyond Visual Line of Sight operations involve flying a drone at distances or in conditions where the remote pilot can no longer maintain direct, unaided visual contact with the aircraft. This marks a fundamental shift from standard Visual Line of Sight (VLOS) flying, where the pilot keeps the drone within sight at all times.

BVLOS unlocks use cases that VLOS simply cannot serve effectively. Linear infrastructure inspections — such as railway lines, power cables, and pipelines — often stretch across tens of kilometres. Agricultural surveys may cover hundreds of hectares. Delivery services must navigate between fixed points separated by significant distances. Search and rescue operations demand coverage of large, sometimes inaccessible areas.

Because the pilot cannot physically see the drone, BVLOS operations introduce risks that do not exist in VLOS flight. The inability to visually detect and avoid other airspace users, the challenge of monitoring the drone's proximity to people and structures, and the complexity of managing contingencies at range all require additional safeguards.

The UK Regulatory Framework for BVLOS

The CAA classifies BVLOS operations under the Specific Category of the UK UAS regulatory framework. This means they cannot be conducted under the Open Category, regardless of the drone's weight or the operator's qualifications.

CAP 722 (Unmanned Aircraft System Operations in UK Airspace) provides the primary guidance. Section 3 of CAP 722 addresses Specific Category operations in detail, including the requirements for BVLOS. The Air Navigation Order 2016 (as amended) provides the underlying legal authority.

Under this framework, any person or organisation wishing to conduct BVLOS operations must obtain an Operational Authorisation (OA) from the CAA. The OA is granted on the basis of a thorough risk assessment using the SORA (Specific Operations Risk Assessment) methodology, supported by a comprehensive Concept of Operations document.

Key Requirements for BVLOS Authorisation

Securing an Operational Authorisation for BVLOS involves meeting several interconnected requirements:

• SORA risk assessment: A complete assessment covering ground risk, air risk, and the determination of the Specific Assurance and Integrity Level (SAIL). This establishes the Operational Safety Objectives (OSOs) that must be met.
• Concept of Operations (ConOps): A detailed document describing the operation, including airspace, equipment, procedures, crew competencies, and contingency plans.
• Detect and Avoid capability: A means of detecting other airspace users and taking appropriate action to avoid collision. The required capability depends on the airspace class and the results of the SORA.
• Command and control link: A reliable and appropriate data link between the ground control station and the drone, with defined performance requirements.
• Insurance: Third-party liability insurance that meets or exceeds the requirements specified by the CAA for the operation in question.
• Crew competency: Remote pilots and other crew members must hold qualifications appropriate to the complexity and risk level of the operation.

The SORA Process in Brief

SORA provides a structured, repeatable method for assessing the risk of a specific UAS operation. It was developed by JARUS (Joint Authorities for Rulemaking on Unmanned Systems) and adopted by the CAA as the standard methodology for Specific Category assessments.

The process follows a logical sequence. First, the operator defines the Concept of Operations. From this, the intrinsic Ground Risk Class (GRC) is determined based on the drone's characteristics and the overflown area. Next, the initial Air Risk Class (ARC) is established based on the airspace environment. Mitigations can then be applied to reduce both the GRC and ARC. The resulting SAIL dictates which Operational Safety Objectives must be satisfied, and to what level of robustness.

The SORA outcome directly shapes the conditions attached to any Operational Authorisation the CAA may grant.

Current State of BVLOS in the UK

As of May 2026, the CAA continues to assess BVLOS applications on a case-by-case basis. The UK Airspace Modernisation Strategy, which includes provisions for integrating drones into the national airspace system, provides broader context for how BVLOS may evolve. NATS, the UK's air navigation service provider, is actively developing UTM (UAS Traffic Management) services that will support the safe scaling of BVLOS operations.

Operators considering BVLOS should engage with the CAA early in their planning process. Pre-application discussions can help identify potential issues before a formal submission is made, saving time and improving the quality of the application.

Steps to Get Started

If you are planning BVLOS operations in the UK, the pathway is clear but demanding:

1. Study CAP 722 Section 3 thoroughly to understand the Specific Category requirements.
2. Define your operation in a draft Concept of Operations document.
3. Conduct a SORA risk assessment based on your ConOps.
4. Identify and implement the necessary mitigations and safety objectives.
5. Prepare your Operational Authorisation application and submit it to the CAA.
6. Engage with the CAA during the assessment process and be prepared to provide additional information or amend your application.

BVLOS operations represent the frontier of commercial drone use in the UK. The regulatory pathway is rigorous, but it exists — and operators who invest in thorough preparation are best positioned to succeed.
