Sub-250g Drone FPV Rules in the UK

What FPV Flying Means Under UK Drone Law

First Person View flying uses a camera mounted on the drone to transmit a live video feed to goggles or a screen worn by the pilot. This creates an immersive flying experience, but it fundamentally changes the pilot's relationship with the aircraft and the surrounding airspace.

The CAA defines Visual Line of Sight as being able to see the unmanned aircraft at all times without the aid of devices other than corrective lenses. When a pilot wears FPV goggles, they can no longer see the drone directly. This means the flight does not meet the VLOS requirement unless additional measures are taken.

Under the UK Regulation (EU) 2019/947 as retained, all flights in the Open Category must be conducted within VLOS. There is no special exemption for sub-250g drones in this regard. The weight advantage of a sub-250g drone gives you freedom to fly closer to people and over uninvolved persons in subcategory A1, but it does not remove the VLOS obligation.

The Competent Observer Requirement

The practical solution for legal FPV flying is to use a competent observer. This person stands beside or near the pilot and maintains direct visual contact with the drone throughout the flight. The CAA expects the competent observer to fulfil several specific functions:

• Maintain unaided visual contact with the drone at all times
• Monitor the surrounding airspace for other aircraft, people, and obstacles
• Communicate clearly and immediately with the pilot about any hazards
• Be positioned close enough to the pilot to enable effective verbal communication
• Be capable of taking over control of the drone if the pilot cannot respond to a hazard

The last point is important. A competent observer is not simply a passive spotter. They should have access to a second controller or be trained to intervene if the pilot needs to remove their goggles quickly. The observer effectively takes on the VLOS responsibility that the pilot has delegated.

Can You Fly FPV Without an Observer?

Flying FPV without a competent observer means you are operating BVLOS. In the Open Category, BVLOS is not permitted. To fly BVLOS legally, you would need to apply for a specific operational authorisation from the CAA under the Specific Category, which requires an operational risk assessment using the SORA methodology or an equivalent process approved by the CAA.

For most recreational and hobbyist FPV pilots, applying for Specific Category authorisation is neither practical nor proportionate. The competent observer route remains the standard approach for legal FPV flying in the UK.

Some pilots argue that using a screen or monitor rather than goggles allows them to maintain peripheral awareness. The CAA has not formally endorsed this interpretation. If the screen is mounted on a controller and the pilot can still see the drone and its surroundings with their unaided eyes while occasionally referencing the screen, VLOS may be maintained. If the pilot is primarily watching the screen and not the drone, VLOS is lost.

FPV Under Article 16 Exemptions

Model aircraft associations such as the British Model Flying Association (BMFA) and FPVUK hold Article 16 authorisations from the CAA. These authorisations allow their members to operate under conditions that differ from the standard Open Category rules, provided they follow the association's operating procedures and fly at approved sites.

Under an Article 16 exemption, FPV flying may be permitted with different observer arrangements or at specific sites where risk assessments have been completed. The exact conditions vary by association and by site. If you fly FPV regularly, joining an association with an Article 16 authorisation can provide a more flexible and clearly defined legal framework.

It is worth noting that Article 16 authorisations are specific to the association and its operating conditions. They do not create a blanket exemption for FPV flying anywhere in the UK. Members must follow the association's rules, fly at designated sites, and comply with any conditions attached to the authorisation.

Equipment Considerations for Sub-250g FPV

Sub-250g drones designed for FPV use are widely available. Popular models in this weight class often include built-in cameras with analogue or digital video transmission systems. When assessing your equipment for legal compliance, consider the following:

• The total weight of the drone including the camera, VTX module, battery, and any antenna must remain below 250g to retain sub-250g privileges
• FPV goggles and the receiver module are worn by the pilot and do not count toward the drone's Maximum Take-Off Mass
• Adding an action camera or upgraded antenna to the drone may push it above the 250g threshold
• Video recording capability on the drone triggers data protection obligations under the UK GDPR if identifiable individuals are captured

Frequencies and Transmission Power

FPV video systems typically operate on 5.8 GHz. In the UK, the use of 5.8 GHz for FPV transmission falls under Ofcom's licence-exempt provisions, provided the transmission power does not exceed 25 mW EIRP. Many FPV systems offer higher power settings of 200 mW, 400 mW, or more. Using these higher power settings without an appropriate amateur radio licence is a breach of Ofcom regulations, not CAA regulations, but it remains a legal compliance issue that FPV pilots should be aware of.

If you hold a Foundation, Intermediate, or Full amateur radio licence from Ofcom, you may transmit at higher power levels on amateur bands. However, the amateur licence does not authorise transmission on all 5.8 GHz channels, and it imposes its own conditions regarding call signs and permissible use.

Insurance and FPV Flying

Sub-250g drone operators are not legally required to hold third-party liability insurance for recreational flights in the Open Category. However, FPV flying introduces additional risk factors that make insurance a practical consideration. The reduced situational awareness inherent in goggle-based flying increases the risk of collision with obstacles or people. Many model flying associations include third-party liability insurance as part of their membership, which is another practical reason to join an association if you fly FPV regularly.

Practical Steps for Legal FPV Flying

1. Register with the CAA as an operator and obtain your Operator ID (required even for sub-250g drones with cameras)
2. Always fly with a competent observer who can see the drone and communicate with you
3. Verify that your drone's total take-off weight, including all FPV equipment, remains below 250g
4. Check Ofcom regulations for your video transmission power and frequency
5. Consider joining BMFA or FPVUK for Article 16 exemption access and insurance
6. Fly at sites where you have landowner permission and adequate separation from uninvolved persons
7. Keep flights below 120 metres above ground level and away from flight restriction zones
