As most are aware, I'm not a Pilot, but have had a long interest in aviation....I thought I could read a map /chart/atlas.
Observations on the screenshots kindly posted by @Dave Phillips
Jepp. mass of overlapping squares/triangles, mix of tma/cta/(c) (d) apparently changing at random from one intersection to the next........sorry, I did a 180 and ran away.
SD....well, a bit more intuitive, some coloured blocks all clearly marked with levels/heights, but it all goes to pot at the lower and RH sides, where these black-edged areas appear to extend 5-deep over Aldergrove and 7-deep over Belfast....very, very confusing....I'll leave it to the CAT peeps and take the ferryboat.
Garmin,- simpler, but what's this? abrupt changes from one box to the next....see lower 2,-105-35 next to 195-35,which, moving up to the top-left of that block, is bounded by a small triangle....no height indication there!...in turn, the upper edge of that triangle abuts a stub off the outer circular bit around Aldergrove heights?
I'll keep clear, there be dragons lurking.
@GrahamB postsaSD filtered screenshot....this is much clearer, but still a lot of jumbled lines with no markings and little indication of how much "clearance" around the Magenta line, whilst trying to cross this series of Tyro-snares.
I appreciate that these things need training and practice to understand, but to low-hours people, this is very-much a complicated, high-workload scenario. there is little that's easy to interpret or grasp. Iwould imagine, if one could sit down and model it in 3D, the whole jungle would become more transparent, but you can't carry a 3 D model in the cockpit, so, somehow, your rookie has to interpret this mass of overlapping 2D areas, into a 3D image and place themselves within it and plan how to transition from one section to the next. or, simply avoid the whole shebang.
Unfortunately, that's not an option for some , where there are all these Controlled Areas, leading to the tightly -constrained "Mig -Alleys" as they seem to be described.
My only surprise is that there are so few incursions.
Anybody recall the kid's game where you all sat round the table and piled hands one on top of the other ? The hand on the table was pulled out and placed on top of the pile....until someone anticipated wrongly and "infringed" by pulling their hand free before it reached the table...they were "out".......similarities
