The VFR Chart Amendment Service previously available on the CAA website at has been transferred across to the AIS website, as of the 28th April 2011. For information the production of the VFR Charts transferred across to NATS/AIS some months ago, so the subsequent transfer of this chart amendment service is a logical progression. The new service is located at www.ais.org.uk  under the VFR Charts heading. The new service will require a user name and password to login, but there remains no charge for this service. If you have any issues please contact vfrcharts@nats.co.uk. The CAA retains some information relating to Visual Flight, including the VFR guide.
