SSR problem is also due to the aproach of aircraft to Barajas and the proximity of cuatro vientos uder the tma and the military airfield 1.5 miles away. Madrids a fantastic city if you get out, explore and get a social network. The area that the airport is in is crap but thats miles outside the city centre. I lived in Madrid for 2 years while i did my ATPLs, had a great time.The IR course is very good, although it is true that instrument aproaches are carried out at other airports.
