In aviation weather, the term "ceiling" is defined as the height above the ground or the Earth's surface at which the lowest layer of clouds or obscuring phenomena (such as fog or smoke) covers more than half of the sky below 20 000 ft. It's essentially the lowest altitude where the sky becomes obscured by clouds or other atmospheric conditions, limiting visibility for pilots.
Ceilings are crucial information for pilots as they directly impact flight operations, especially during take-off, landing, and navigation. Low ceilings can significantly affect visibility and may require specific instrument procedures or alternate routes to ensure safe flight operations. Knowing the ceiling height allows pilots to make informed decisions about flight planning, route selection, and approach procedures, ensuring the safety of the flight and its passengers.
