LHR routings
On BBC Surrey news there was a report about anger and protests in Ascot over new Heathrow routings as part of a trial that's going to last 5 months. As I live close by but have not noticed any change in noise or routings I am curious to know what this is. It does not appear on the NATS site although there are information blocks about other routing changes made last year. Any one of the UK ATC folks who use PPRUNE able to let me know what this is all about
Thanks in advance
