My original post was concerning airspace so apparently complex one can't work it out from the chart.
So it is no good talking about ATC being helpful, because no matter how helpful ATC might be
usually, if one is flying VFR one
must have a Plan B which is wholly OCAS and which one can fall back onto at any time.
Or maybe some pilots just fly and bluff their way along... I never tried that
I do know it would not work significantly south of Switzerland, either.
I too used to fly through e.g. Belgium at FL080 or whatever, VFR, under radar control, with ATC giving me headings. A very enlightened attitude compared to the UK. But this could not be assured up front. And an OCAS route via Belgium was at a very low level and a little tricky.
I still don't see how Jepp arrive at that airspace depiction, reltive to the Swiss national chart, and have apparently had it for 1-2 years without correcting it. Does the Swiss chart have an altitude limit which somehow strips out all that airspace?
