If the SIDs out of EDI headed the same way initially for "environmental" reasons ie noise...
and given the increasing priority that politicians, environmentalists and people generally are giving to reducing emissions for the sake of the environment....
Is it not time to start looking at ways to minimise aircraft sitting at the holding point burning many many kg of fuel, in order that no departures turn early and cause some noise for someone on the ground?
After all, an early turn might cause more noise for some people, but it also reduces noise for the other people who would have been overflown by the SID but now don't!
Have I missed something here? Or am I just cynical 'cos I've never been able to afford a house in any village that has a SID bent around / away from it?!
