Update by Charles Kirwan-Taylor, Corporate Affairs & Sustainability Director

11 November 2016

Charles Kirwan-TaylorThe six months monitoring period of the amendment to Route 4 ends at 23:59 on 26 November 2016. As I have previously outlined, the Civil Aviation Authority (CAA) has been receiving monthly data packages from Gatwick Airport regarding route performance and feedback received, this activity however will cease with the end of the monitoring period at which time we will forward our final data package to the CAA and publish a data summary to this blog.

We will continue to monitor Route 4 performance in common with all other departure routes from Gatwick Airport and report accordingly in our Flight Performance Team reports to the Noise and Track Monitoring Advisory Group and the Gatwick Airport Consultative Committee; details of which are available online.

The CAA has undertaken to evaluate the data and decide whether the amendment has been a success or otherwise approximately three to four months after the end of the monitoring period.

After the cessation of the monitoring period:

  • The current amendment to Route 4 will remain in place at least until we hear from the CAA. This is because the route flown over the previous six months is not a trial but an amendment as required in the CAA Post Implementation Review. Should the CAA deem this amendment to be unsuccessful, it would be at that stage when we would consider other options available.
  • Should the airport be required to return to a conventional navigation procedure in the event the CAA deems the amendment to be unsuccessful, this would not be a permanent solution but would only be in place until alternative solutions are developed. This is because Performance Based Navigation (PBN) Standard Instrument Departure routes are UK CAA policy under international implementation policies and are expected to be mandated in terminal airspace from 2017.
  • The Route 4 dedicated email address will close at 23:59 on 26 November 2016. After this time, the method for registering noise complaints will be via our dedicated noise website
