In aviation, ceiling is a measurement of the height of the base of the lowest clouds (not to be confused with cloud base which has a specific definition) that cover more than half of the sky (more than 4 oktas) relative to the ground.
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 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 ...
Aerospace engineering – is the primary field of engineering concerned with the development of aircraft and spacecraft. [13] It has two major and overlapping branches: Aeronautical engineering and Astronautical Engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
BKN003 OVC010 indicates a broken (5 ⁄ 8 to 7 ⁄ 8 of the sky covered) cloud layer at 300 ft (91 m) above ground level (AGL) and an overcast (8/8 of the sky covered) layer at 1,000 ft (300 m). M02/M02 indicates the temperature is −2 °C (28 °F) and the dew point is −2 °C (28 °F).
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration 's (FAA) Instrument Flying Handbook defines IFR as: "Rules and regulations established by the FAA to govern flight under ...
A broken sky has thin strips of clear blue peeking through abundant clouds. Broken clouds don’t form a uniform layer across the sky; they can be thinner in spots and thicker in others.
