I just wanted to know if there are specifications for runway usage at MIA. I was at the 94th squadron a couple of days ago and looking on 09R what I saw the most where cargo planes (Tampa, Centurion, Gemini, Amerijet) but hardly saw any passenger heavies t/o or landing on 9R except for a Martinair 763. I know in airports such as BOG 13R is mostly used for heavies coming from overseas, and 13L is for smaller a/c serving domestic routes. Is this the case in MIA? What is a good place to spot on 12 and 9L?
