So I am trying to hammer the VFR airspace clearance rules into my head. My skull is proving quite resistant to the new knowledge. Taken 2x online ground school classes and watched the videos. Looked at the FAA table, the diagrams and the airspace triangles. All good and accurate information but not getting into my head. I have done a lot of coding in my life, and I came up with this set of rules, which fits in my head nicely: Over 18K: Not VFR Over 10K: 5-111 (5 SM visibility, 1000 FT above, 1000 FT below, 1 SM lateral) Under 10K: 3-152 (3 SM visibility, 1000 FT above, 500 FT below, 2000 FT lateral) Except: Class B: 3-CLR (3 SM visibility, clear of clouds) Except: Class G daytime: 1-152 (1 SM visibility, 1000 FT above, 500 FT below, 2000 FT lateral) Except: Class G daytime under 1200 feet AGL or SVFR: 1-CLR (1 SM visibility, clear of clouds) Here they are in an abbreviated format, assuming you are not going over 18K or into Class B: 10K+: 5-111 10K-: 3-152 Except: Class G daytime: 1-152 Except: Class G 1200- daytime: 1-CLR For me, that format is very simple to remember and understand. I think they catch everything, do you see anything these rules leave anything out? Comments, thoughts, ridicule welcome.
