Respective Grid MORAs 82 & 88 (rounded up to nearest 100' +2000' as above 6000)
Both are above the Transition Altitude 6000' and converted to FLs, ensuring terrain clearance in the event of low QNH.
Not too sure how that ensures terrain clearance in the case of low QNH.
If during a bad spell of weather (which I have seen down there) when the QNH drops significantly, then you are getting closer and closer to terrain. Just seems very odd to reference MSA on a standard pressure and no QNH.
KISS anyone. Maybe it's just to confuse us!?
I emailed the AIP nav of Spain but I'm not hopeful of a response.
