CAA Updates UK Night Drone Rules For Open Category

Flying a drone at night in the UK has been clarified with updated guidance from the Civil Aviation Authority. The latest update explains how existing regulations apply in practice, with a strong focus on visibility and safe operation after dark. This is relevant for both recreational and professional pilots operating in the Open Category.

What Has Changed For Night Drone Flying

The requirement for visible lighting forms part of UK drone regulations introduced on 1 January 2026. More recently, the CAA has issued further guidance to clarify how these rules should be applied during real world operations.

Drones flown at night must display a green flashing light for the full duration of the flight. This ensures the aircraft remains visible from the ground and supports safe visual line of sight. The responsibility sits with the remote pilot to confirm that the light is active before take off and continues to function throughout the operation. If the light becomes inactive at any stage, the flight would no longer meet the required standard.

The light must also be positioned in a way that allows it to be clearly seen from the ground at all times. A poorly placed or obstructed light may not provide sufficient visibility, even if it is switched on.

What This Means For Drone Pilots

For many pilots, this update introduces a simple but important step in their pre flight checks. Not all drones are equipped with lighting that meets this requirement, particularly smaller or older models. In these cases, a suitable green flashing light must be securely fitted to the aircraft.

Some newer classified drones may include compliant lighting as part of their design, but this is not guaranteed across all models. Pilots should check their drone specifications and user manual to confirm whether additional equipment is required.

It is also important to consider the impact of adding accessories. Even small additions can increase the overall weight of the drone, which may affect its classification and how it can be operated within the Open Category.

Common Compliance Risks To Avoid

One of the most common risks during night operations is related to automatic settings. Certain drones may reduce or switch off lights when recording video or taking photos. If this occurs during flight, the operation may become non compliant without the pilot realising.

Another consideration is ensuring the light remains consistently visible. Environmental factors, positioning and mounting can all affect how clearly the light can be seen from the ground. Taking the time to check these details before flying can help avoid unnecessary issues.

FAQs

Do I need a flashing light to fly a drone at night in the UK?

Yes, a green flashing light is required for all Open Category night flights.

What if my drone already has lights built in?

You must ensure they meet the requirement and remain active during the entire flight.

Can I use any type of light on my drone?

No, the light must be green and clearly visible from the ground while flying.

Will adding a light affect how I can fly?

It can, especially if it changes the total weight of your drone.

Do sub-250g drones need a light at night?

Yes, the requirement still applies regardless of drone size.

Conclusion

The latest CAA guidance provides clearer direction on how night flying rules should be followed in the UK. While the requirement itself is straightforward, it places greater responsibility on pilots to ensure their equipment, setup and in flight awareness remain compliant at all times.
