For those that don’t know, IMC stands for Instrument Meteorlogical Conditions, meaning no VFR pattern work.
You can find the FAA minimums here:
I had to deny a lot of patternwork at KLAX tonight, and I’m sure many were confused, as it had nothing to do with traffic. So, to explain, when you’re doing VFR patterns at a field, it can’t be IMC.
Let’s take a gander at the field and the METAR:
Visibility is 1/4 sm, well under 3, and the ceiling with the fog listed as indeterminate, estimated at 300 feet. If you can’t see the ground beneath your feet, it’s hard to see the runway.
In conditions such as these, VFR patterns are simply impossible. If you were one of those confused by being denied VFR patterns with no traffic-volume considerations, this is why.
