VFR Weather Minimums

Here is another way to try to remember all the VFR weather minimums you packing to you mind when you learned to fly. I have found that it may be easier to remember VFR weather minimums if they were organized by altitude rather than a list of airspace. There are also some memory aids that help to make sense of it all.*

The Memory Aids

  • Above 10,000' MSL is where "F-one elevens" ( F-111 is a military jet) fly.
    • F = Five miles visibility
    • 1 = One thousand feet Above the clouds
    • 1 = One thousand feet Below the clouds
    • 1 = One mile Horizontal separation from clouds
  • Below 10,000 MSL and above 1200' AGL in any airspace, except B and G at night, is a big chunk of the sky where a LOT of training happens. So just remember there are three Cessna 152's flying around in that airspace that includes classes C,D, E, and G at night.
    • Three = Three miles visibility
    • 1 = One thousand feet Above the clouds
    • 5 = Five hundred feet Below the clouds
    • 2 = Two thousand feet Horizontal separation from the clouds
  • In the Midwest there is very little class G airspace ABOVE 1200' AGL. Since the amount of class G airspace above 1200' AGL is so small only one Cessna 152 can fly around in the airspace during the day.
    • One = One mile visibility
    • 1 = One thousand feet Above the clouds
    • 5 = Five hundred feet Below the clouds
    • 2 = Two thousand feet Horizontal separation from the clouds
  • There are two exceptions that have to be memorized.
    • Class G airspace below 1200' AGL during the day requires 1 mile visibility and clear of clouds
    • Class B airspace 3 miles visibility and clear of clouds

To review, think of F-111s flying high and fast above 10,000' MSL needing lots of visibility and cloud separation. Also note that 152 ; above, below and horizontal is alphabetical.
