Thanks: delay due weather in UK. The info on spanish airfields very useful. its more to do with GA procedures, booking ahead PPR , fuel etc. ATPL with a Bulldog ac max 3 hours endurance and looking for avgas . Where to avoid and crossing the myriad of restricted areas. I would plan to skirt around and below but as a lot of airspace is or appears to be based on AGL not a level or an altitude it appears that you will spend a lot of time flying below 1000ft between areas of high ground? Therefore poor radio comms.
