I have been cleared by Sevilla to descend to an altitude that would uncontrovertibly impacted the terrain
Not wanting to get in an argument with you GF, you've way more experience in this than me. But this quote above from you is why I said you assert:
"that Spannish atc will clear an aircraft to an altitude which does not provide terrain clearance"
Platform altitude, guess I'll have to look that one up, and see how it affects atc cleared altitudes.
So...I was just trying to understand how the atc system works. Maybe I don't understand the nuances, or maybe the controller made an error, or maybe I'm missing some crucial information. But this thread has produced posts that shows terrain clearance situations that I don't have a clear understanding of.
Bookworm, as always, digs up interesting docs. Will have to read closely and see how this fits in to the thread. Unless someone else can straighten me out
