Cloud-cover symbols used on weather teleprinters and aviation reports in the US [6] In the early 20th century, it was common for weather maps to be hand drawn. The symbols for cloud cover on these maps, like the modern symbols, were drawn inside the circle marking the position of the weather station making the measurements.
The height above the ground or water of the base of the lowest layer of cloud below 6000 meters (20,000 feet) covering more than half the sky. [2] United Kingdom The vertical distance from the elevation of an aerodrome to the lowest part of any cloud visible from the aerodrome which is sufficient to obscure more than half of the sky. [3] United ...
At distances nearing infinity, the scattered light is therefore white. Distant clouds or snowy mountaintops will seem yellow for that reason; [12] that effect is not obvious on clear days, but very pronounced when clouds are covering the line of sight reducing the blue hue from scattered sunlight.
The flight visibility at the cruising altitude of the aircraft must be at least 5 miles and the weather at the destination aerodrome must be forecast to have a sky condition of scattered cloud or better, a ground visibility of 5 miles or greater with no forecast of precipitation, fog, thunderstorm or blowing snow, and that these conditions must ...

Although chaff produces large amounts of scattered reflections potentially clogging a radar display it is easily filtered by virtue of it moving relatively slowly through the sky. Radar can make use of the doppler effect to distinguish between chaff and target aircraft which are fast moving.
Space Shuttle Atlantis on a Shuttle Carrier Aircraft. Aeronautics is the science or art involved with the study, design, and manufacturing of air flight-capable machines, and the techniques of operating aircraft and rockets within the atmosphere.
Aviation engineering is a branch of engineering which deals with airspace development, airport design, aircraft navigation technologies, and aerodrome planning. It also involves the formulation of public policy, regulations, aviation laws pertaining to airspace, airlines, airports, aerodromes and the conduct of air services agreements through treaty.
