WOW. Good stuff in here as I sit watching the clock waiting for my class D COAS to process - over FIVE MONTHS now. JO 7200.23 http://www.faa.gov/documentLibrary/media/Order/FAA_JO_7200_23_2.pdf Thanks for finding this Quadrocopter! "Air traffic procedures in controlled airspace. This gets interesting around page 19 where maps with altitude block segments will define what is immediately approved by headquarters for flights within controlled airspace."
