Question

Based on IFR outlook criteria in a GFA what would indicate VFR, MVFR, and IFR weather?

a. VFR: Visibility 6 miles or more, MVFR: Visibility 3 to 6 miles, IFR: Visibility less than 3 miles
b. VFR: Visibility 3 miles or more, MVFR: Visibility 1 to 3 miles, IFR: Visibility less than 1 mile
c. VFR: Visibility 5 miles or more, MVFR: Visibility 2 to 5 miles, IFR: Visibility less than 2 miles
d. VFR: Visibility 4 miles or more, MVFR: Visibility 1.5 to 4 miles, IFR: Visibility less than 1.5 miles

Answer 1

The correct IFR outlook criteria indicate VFR weather at a visibility of 3 miles or more, MVFR with visibility between 1 to 3 miles, and IFR with visibility less than 1 mile.

Step-by-step explanation:

The criteria for categorizing flight visibility conditions in a Graphical Forecast for Aviation (GFA) include VFR (Visual Flight Rules), MVFR (Marginal Visual Flight Rules), and IFR (Instrument Flight Rules). For conditions to be considered VFR, visibility must be 3 miles or more and the ceiling greater than 1,000 feet. MVFR conditions are defined by visibility between 1 to 3 miles and/or a ceiling between 500 to 1,000 feet. Lastly, IFR conditions persist when visibility is less than 1 mile and/or the ceiling is less than 500 feet. Therefore, the correct answer is b. VFR: Visibility 3 miles or more, MVFR: Visibility 1 to 3 miles, IFR: Visibility less than 1 mile.
