Its a wonderfly clear day here in South Essex and I'm looking out of my westerly facing window at work watching the airliners going round the Lambourne stack. Its more interesting than what I'm paid to do
What I was wondering was at what height are aircraft brought into the stack and what is the minimum height to which they will be descended? I've always assumed its above 2500' as thats the base of the LTMA at LAM Is there an optimum height at which you would be aiming to get the aircraft out of the stack and on route?
Does the size of the racetrack vary, as increasingly I'm seeing aircraft extending further to the east?
