IMC
Instrument meteorological conditions (IMC) are the most pertinent hazard for all general aviation pilots. IMC are meteorological conditions expressed in terms of visibility, distance from cloud, and ceilings less than the minima specified for visual meteorological conditions. Visual meteorological conditions (VMC) essentially require good visibility and cloud clearance. The specific clearances required depend of the type of airspace and the country that you are flying in. For example, inside controlled airspace the distances are shortened. Now, why is it that over 25% of general aviation fatalities are caused by flying VFR into IMC? It comes down to training, equipment, and disorientation. As many are aware, there are two primary sets of flight rules, visual (VFR) and instrument (IFR). When you reach the milestone of your private pilots license (PPL), you are licensed and trained to fly under VFR. Though you may go through a small bit of training t...
