A and C
Hear, Hear.
As another poster has already said, NW is further complicated by glider traffic.
There are complications arising from the lack of 'deadside' when gliding is active, but of course gliders do not always appear where you expect them to either and many are non radio, so cannot advise of their position and intentions.
This is not an attack on glider pilots, but a re-iteration of a serious point that Skylark 4 (an experienced glider pilot) made in another thread some time ago.
Parascending also occurs sometimes - I think we can discount the model aeroplane flying as being pretty safe though
So your comment about airmanship is spot on from my perspective.
I love to watch a well executed run and break by a good pilot, but we don't want any more tragedies as you rightly say.
