What type of visibility does "P" indicate in meteorological shorthand?

The letter "P" in meteorological shorthand stands for "Good visibility.” This term is often used in aviation and meteorological reports to indicate that visibility is above a certain threshold, making it suitable for flying. In aviation, good visibility is critical for safe operations, as it allows pilots to see and avoid obstacles, other aircraft, and to navigate effectively.

In contrast, other terms like "poor visibility" or "partial visibility" designate less favorable conditions that can impede a pilot's ability to safely operate an aircraft. Good visibility reflects clarity in the atmosphere, which is essential for effective communication among pilots and air traffic controllers, as well as for the overall safety of flight operations.
