What term defines weather conditions below minimum for flight under visual flight rules?

• A. IFR Conditions
• B. IFR Over-the-Top
• C. Instrument
• D. Gyroplane

Answer: (A)

Weather conditions that are below the minimums required for flying visually are called IFR conditions. In these conditions you don’t have the visual references needed to safely fly VFR, so flight would be conducted under instruments and the Instrument Flight Rules. For pilots who are not equipped or authorized to fly IFR, such as some sport pilots, these conditions mean you should not fly. The other terms listed don’t describe the weather situation: one refers to a specific IFR routing scenario, another is just the word “instrument” without weather context, and the last describes an aircraft type rather than weather.
