When a GFA (Graphical Forecast for Aviation) Outlook indicates "IFR," it signifies that the flight conditions are expected to fall below the minimum criteria that define Instrument Flight Rules. Specifically, this includes ceilings (the height of the lowest layer of cloud cover) that are below 1,000 feet, and/or visibility that is less than 3 statute miles. This classification is crucial for pilots, as IFR conditions require the use of instruments for navigation and landing, rather than visual references.

The thresholds for IFR conditions are established to ensure safety during flight operations, especially in lower visibility or cloud-covered scenarios. Understanding these parameters helps pilots make informed decisions regarding flight planning and the necessity for instrument flight capabilities. The choice indicating ceilings less than 1,000 feet and/or visibilities less than 3 statute miles correctly encapsulates the definition of IFR conditions, reinforcing the understanding needed for safe aviational practices.
