1,000 feet and 3 miles.
1,000-foot ceiling and 3 miles visibility.
ceiling and visibility unlimited
From a practical standpoint, yes. AIM 7-1-31 says, "For aviation purposes, the ceiling is the lowest broken or overcast layer [of clouds], or vertical visibility into an obscuration." It goes on to explain that vertical visibility is an indefinite ceiling height where total obscuration is indicated. That said, 14 CFR 1.1, under "ceiling", makes no mention of vertical visibility.
CAVU = Ceiling And Visibility Unlimited.
Ceiling 1,000 feet overcast and 3 to 5 statute miles visibility.(Refer to figure 16.
The blue box with number on the VFR terminal area chart is the ceiling of class D airspace in hundreds of feet ( A minus ceiling value indicates surface up to but not include that value.)
This makes no sense.
In aviation, "CAVU" stands for "ceiling and visibility unlimited," meaning there is no cloud below 10 000 feet and visibility is 10 statute miles or greater. Also used is the term "CAVOK," meaning no cloud below 5000 feet and visibility of 6 statute miles or greater.
It is CAVU, not ca bu. CAVU is an acronym that stands for "ceiling and visibility unlimited".
