Definition of Instrument Meteorological Conditions (IMC)
Instrument Meteorological Conditions (IMC) refer to weather conditions that require aircraft to operate using Instruments Flight Rules (IFR) due to visibility, ceiling, and cloud distance that do not meet the minimum criteria required for Visual Meteorological Conditions (VMC). IMC differs from VMC as it requires the use of flight instruments and ground-based navigation systems to operate safely, while VMC allows pilots to navigate visually. The IMC conditions can include low visibility caused by thick fog, heavy rain, or snow, which make it difficult for pilots to see the runway or other aircraft in close proximity. Moreover, IMC can lead to icing, turbulence, thunderstorms, and strong winds, which can cause accidents. As a result, pilots must obtain proper certification, training, and instruments to operate effectively during IMC conditions. Overall, IMC increases safety while flying under challenging weather conditions, making instrument flying a crucial skill for pilots.
