Arrival routes into Newcastle
 

Morning all. Any ideas why nighttime arrivals into Glasgow and Edinburgh from the South East (last KLM from Amsterdam, holiday charters from Greece Turkey etc.) fly in a straight line from the mid-North Sea right over Newcastle (NCL) and into the Central Scotland area, while the same arrivals into NCL do a dog leg to the south of what would be the most direct route?

I understand that during the day there is often military activity from the Vale of York out to the Yorkshire coast, but didn't think that lower-level airspace is active overnight? Some of the aircraft performing the aforementioned 'dogleg' actually route over the Yorkshire coast (I'm on FR24 watching EXS514 do that now while EXS862 (Bodrum - Edinburgh) just flew straight as a die from the North Holland coast to overhead NCL...

Scottish TMA arrivals will be on high level routes until NATEB only leaving UIR after NATEB. Where as NCL inbounds would have to descend into class G airspace South East of NATEB sometimes the military radar service to do that is not available.

Thanks for the explanation, 10DME. Makes sense :)
