If I get an ATC instruction that I don't think is safe or clear, I'm certainly going to query it
And indeed we would expect you to, however an "Unsafe clearance" such as you suggest is not really what is being discussed within the context of this thread. (Standing agreements and descent planning as a primary argument)
go back to my point again however..why the big secret? can't you ATCO's just accept that by giving us the information it helps us as well?
Again back to my point,
there is no big secret. Why can't you accept that the information that is (or is not) published is done so by Directorate of Airspace Policy at the CAA and not by Air Traffic Control Units. The discrepancy of the amount of information that is submitted for publication against what is actually published, is bigger than you think. And this has related to potentially unsafe IAP Plates! Perhaps it is something the UKFSC could look at if it is such a big concern to all operators.
Perhaps you should look further up the food chain before bashing ATCO's on here for doing their job?
