Blissbak,
From 8 to 20 wouldn't be a problem.
From 8 to 5, they'll have to deal with wake turbulence, which they didn't know in ACCs... I would have thought planes, pilots and passengers would have been worth just a bit more than a flyer.
What is a radar endorsement when controller has benefitted NO training at all for years ?
Not Long Now,
5 miles regardless of wake categories
Isn't there already a separation of 6 miles in UK, between H and L ?
With the new classification, it will be 8 between A and F.
