• Rules and regulations are in place that pilots, air traffic controllers, aircraft engineers and others have to follow to ensure the highest levels of aviation safety.

    If you think you have witnessed a breach of one of these rules or regulations then you can report it to us.

     For all issues relating to drones or unmanned aircraft contact the Police on 101.

    What we can investigate

    • Low flying 
      In general, unless they are landing or taking off, an aircraft should be 1,000 ft over a built up area or otherwise 500ft from people, buildings etc. It’s extremely difficult to judge aircraft height above the ground and distance from objects but if you have evidence of the height/distance, such as photographs, we can investigate (see note). To enable us to trace the aircraft concerned you would ideally have its registration. For UK aircraft this is normally G- followed by four letters and is on the side and wing of the aircraft.

    Note: When using FlightRadar24 as a position source, it should be noted that, as the FlightRadar24 website explains, the altitude displayed is not necessarily indicative of an aircraft's height above ground. FlightRadar24 is therefore not considered to be a reliable source of evidence of an aircraft's position.

    • Unsafe flying 
      We can investigate incidents of unsafe flying. You need to provide evidence of the incident and to enable us to track the aircraft concerned you would ideally have its registration. For UK aircraft this is normally G- followed by four letters and is on the side and wing of the aircraft. Examples include unapproved and dangerous low aerobatics or a helicopter landing in a place that puts people or property in danger (helicopters are allowed to land away from airfields providing they can do so safely and they have the landowners’ permission).

    Other examples we can investigate include aircraft flying without the correct approvals, companies or individuals charging for flights without the correct certificates, pilots flying without the correct licences and engineers undertaking unapproved work.

    Complaints dealt with by other agencies

    • Drones
      If you think a drone is being flown dangerously then please immediately contact the local police on 101.
    • Low flying military aircraft 
      For complaints about low flying military aircraft contact lowflying@mod.uk or call 01780 417 558
    • Criminal activities and security risks 
      If you think an aircraft is being used for criminal purposes or is a security risk then immediately contact Crime Stoppers on 0800 555 111 or call your local police on 101 and quote Project Pegasus. 

    How to report a potential breach of aviation law

    If you think you have witnessed a breach of aviation law then you can make an online report.

    If there is sufficient evidence (such as the aircraft registration) then we will investigate. Once we have conducted an initial review we will contact you to let you know what action we will be taking. Normally this will be within 20 working days.
