What is VMC and IMC in aviation?

VMC and IMC are aviation terms used to describe meteorological conditions during flight. VMC stands for visual meteorological conditions, and IMC stands for instrument meteorological conditions.Click to see full answer. Consequently, what is VMC in aviation?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.Also, what is the difference between VFR and VMC? Visual flight rules (VFR) are just that, a set of rules adopted by the FAA to govern aircraft flight when the pilot has visual reference. On the other hand, visual meteorological conditions (VMC) are expressed in terms of visibility, distance from clouds, and ceiling meeting or exceeding the minimums specified by VFR. Secondly, what does IMC stand for in aviation? Instrument meteorological conditions What is inadvertent IMC?Visual flight rules (VFR) flights that inadvertently or intentionally enter into instrument meteorological conditions (IMC) continue to be a significant safety hazard to general aviation (GA) flights.
