What does IMC mean?

What does IMC mean?

• A. Intra-Meteorological Condition
• B. Instrument Meteorological Conditions; Expressed in terms of visibility, distance from clouds and ceiling less than the minimum specified.
• C. Integrated Meteorological Control
• D. Instrumental Maneuvering Conditions

Answer: (B)

IMC stands for Instrument Meteorological Conditions. This describes weather conditions that require pilots to rely on cockpit instruments rather than outside visual references because visibility, distance from clouds, and ceiling are below the minimums published for visual flight. When IMC is present, operations switch to IFR with instrument-based navigation and procedures. The other terms listed aren’t standard aviation terminology, so they don’t describe the conditions in which flight must be conducted under instrument rules.
