'...CONTINUED VFR INTO IMC...'

摘要

According to the AOPA Air Safety Institute's 2010 Nail Report, "The most common type of weather accident, and one of the most consistently fatal, continues to be the attempt to fly by visual references in instrument meteorological conditions, often called "VFR into IMC." There were 14 VFR-into-IMC accidents in 2009, of which 12 (86%) were fatal. The same lethality was seen in thunderstorm encounters, where six out of seven were fatal...." The chart at right, adapted from the report, provides graphic evidence of how these numbers relate to all weather-related accidents.
