CAVU

CAVU – Ceiling and Visibility Unlimited

CAVU is a term commonly used in aviation to indicate the ideal flying conditions. It represents the state where the ceiling and the visibility are unlimited, allowing for a safe and comfortable flight experience.

The ceiling refers to the height of the lowest layer of clouds in the atmosphere, and in the case of CAVU conditions, there are no clouds at all. This means that the pilot has an unobstructed view of the sky and the ground below, which is essential for safe navigation. In addition, the clear sky allows for easy navigation by using celestial landmarks such as stars or the sun.

Visibility is also a critical factor in flying, as it determines how far a pilot can see and therefore react to obstacles, terrain, and other aircraft. In CAVU conditions, the visibility is at least 10 miles, which provides an excellent view of the surrounding area and allows for early detection of potential hazards.

Overall, CAVU conditions provide the perfect atmosphere for an excellent and safe flying experience. However, pilots must be aware that weather conditions can change rapidly, and even the slightest reduction in either the ceiling or visibility can adversely impact the flight’s safety.
