During the course of the event competitors or their representatives are not permitted to use, or be directly or indirectly concerned in the use of, helicopters or fixed wing aircraft in the vicinity of the event (whether in connection with servicing, aerial surveillance or any other reason whatsoever), unless previous authority has been obtained from the organisers in writing. Any application must be made at least 14 days before the event. Helicopter Commanders are reminded that landing a helicopter on private land without the Landowner’s permission is an offence. In accordance with CAA Regulations, no aircraft is allowed within 500 feet of the route, or within 3000 feet of any large crowd. Any Helicopter Pilots wishing to land in the vicinity of any rally venue or stage will have to make their own private arrangements. In recent years the organisers have received complaints from Landowners about helicopters landing on their property without permission and about helicopters causing distress to animals. There have also been safety issues where spectators have been unaware of the approach of a competing car due to the noise of a low flying helicopter. Consequently all marshals have been instructed to record the details of any helicopter activity in their area, and where appropriate these details will be provided to the Landowner and/or forwarded to the Civil Aviation Authority.
