VFR / VMC visibility requirements in the US. In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft.
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.
It usually happens when the aircraft is inside controlled airspace, and the local weather is less than the minimums required for flight under visual flight rules (VFR) within the airspace in question. [5] Note that an aircraft might be able to fly under SVFR even in Class A airspace, where instrument flight rules (IFR) flight is the norm. [6]
A pilot's view of the runway just before landing in thick fog at night. In aviation, instrument meteorological conditions (IMC) are weather conditions that require pilots to fly primarily by reference to flight instruments, and therefore under instrument flight rules (IFR), as opposed to flying by outside visual references under visual flight rules (VFR).
Sunday was a rough day for many air travelers, and some are still struggling to get to their destinations. Nearly 2,500 U.S. flights were canceled and more than 9,800 flights were delayed Sunday ...
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 ...
