Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will commission research on the (a) potential impact and (b) prevalence of interference of 5G technology on the radio bandwidth of aircraft navigation systems.

The UK Civil Aviation Authority (CAA) is aware of the concerns around 5G and is actively monitoring any potential risk of 5G interference to radio navigation aids both nationally and internationally.

The risk of aircraft equipment failure remains inherently low but is under constant review. To date no UK or international reports of radio altimeter failure have been directly attributed to 5G technology. The CAA has issued a Safety Notice across the industry and continues to monitor any concerns that the 5G network could affect equipment onboard aircraft. It will keep this under review and update it to reflect UK and international developments.
