Pattern Altitude
I understand that the METAR reports CLR for 0/8, FEW for 1-2/8, SCT for 3-4/8, BKN for 5-7/8, and OVC for 8/8 - and for different cloud bases. I even learned a new term, "oktas," while looking around on the net.
However, I'm still curious about how exactly this is done visually, by a human observer. The geometry confuses me. Is it done by looking up and dividing the dome into 8 pie slices? A visual sweep over a worst-case arc? An estimate?
What exactly do the do? If relevant, what does an okta look like?
I can't seem to find a good explanation.
Thanks!
