Can someone please tell me what CAVOK means? Also, what is the reason for the CAVOK setting within ActiveSky wxRE?Thank you in advance for your help.

Somebody will correct me but from what I remember it means Clear Above Visibility OK or something similar. Basically it means good (flying) weather at that location.regards,DaveVancouver

Also Ceiling And Visibility OK.regards,DaveVancouver

I found the answer!The term CAVOK is an acceptable contraction (meaning Ceiling and Visibility OK) for international use. It indicates that: No clouds exist below 5,000 feet or below the highest minimum sector altitude, whichever is greater, and no cumulonimbus are present. Visibility is 10 kilometers or more and, No precipitation, thunderstorms, sandstorm, duststorm, shallow fog, or low drifting dust, sand or snow is occurring.Now we'll all know what CAVOK means.
