Note:
- CAVOK (Ceiling
And Visibility
OK) replaces visibility, weather
and clouds if: visibility >=10km; no cloud below 5000 ft (1500m)
or below the highest minimum sector altitude, whichever is greater
and no CB(Cumulonimbus); and no precipitation, TS, DS, SS, MIFG,
DRDU, DRSA, or DRSN. (not in North America)
- NSC (No Significant Cloud) replaces clouds if: no cloud below 5000ft (1500m)
or below the highest minimum sector altitude, whichever is greater
and no TCU(Towering CUmulus) or CB(Cumulonimbus). (not in North America)
NCD (No Cloud Detected) replaces clouds if: no cloud below 5000ft (1500m)
or below the highest minimum sector altitude, whichever is greater above the sensor, usually in AUTO ob. (not in North America)
