What does "CAVU" stand for in aviation weather?

In aviation weather, "CAVU" stands for "Ceiling and Visibility Unlimited." This term is used to describe ideal flying conditions characterized by a clear sky and excellent visibility. When weather is referred to as CAVU, pilots can expect unobstructed views for navigation and flight, which is both safe and conducive to effective flight operations. CAVU conditions indicate that there are no significant obstacles to both vertical and horizontal visibility, allowing for full awareness of the environment.

The terminology is crucial for pilots as it helps them assess whether it is suitable to fly, given that weather conditions significantly impact flight safety and performance. Understanding CAVU helps reinforce the importance of meteorological information in flight planning and operations.
