In uncontrolled airspace there is less risk of a VFR aircraft colliding with an instrument flight rules (IFR) aircraft emerging from a cloud, so aircraft are permitted to fly closer to clouds. An exception to this rule is class B airspace , in which ATC separates VFR traffic from all other traffic (VFR or IFR), which is why in class B airspace ...
The Canadian rules specify that an aircraft may be operated in VFR OTT flight during the cruise portion of the flight during the day, at a vertical distance from clouds of at least 1000 feet. When the aircraft is operated between two cloud layers, the vertical distance between the layers must be at least 5000 feet.
d. A VFR CLOUDS/WX section i. Contains a 12-hour specific forecast, followed by a 6-hour categorical outlook; ii. Broken down into geographical areas, and/or states; iii. Describes cloud and weather affecting VFR flight operations, including precipitation, thunderstorms, and sustained surface winds 20 Kts or greater. Also includes visibility ...
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.
"Few" = 1–2 oktas SCT "Scattered" = 3–4 oktas BKN "Broken" = 5–7 oktas OVC "Overcast" = 8 oktas, i.e., full cloud coverage TCU: Towering cumulus cloud, e.g., SCT016TCU CB: Cumulonimbus cloud, e.g., FEW015CB VV "Vertical Visibility" = Clouds cannot be seen because of fog or heavy precipitation, so vertical visibility is given instead.
Cleveland, Ohio, and Erie, Pennsylvania, have a chance of rain mainly in the morning, but scattered cloud cover may be slow to exit the area even after the rain ends. The extent of the cloud cover ...
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 ...
VFR requires a pilot to be able to see outside the cockpit to control the aircraft's altitude, navigate, and avoid obstacles and other aircraft. [3] Governing agencies establish specific requirements for VFR flight, including minimum visibility, and distance from clouds, to ensure that aircraft operating under VFR are visible from enough distance to ensure safety.
