Questions

The current visibility cаn be used tо determine the flight cаtegоry оf аn airport: If visibility is less than 3 miles, instrument flight rules (IFR) apply. If visibility is at least 3 miles, but less than 5 miles, conditions are marginal visual flight rules (MVFR). If visibility is 5 miles or more, conditions are visual flight rules (VFR). You write the following program to prompt the user for the visibility and determine the flight category: 1 visibility = int(input("Enter visibility in miles: ")) 2 3 if visibility >= 5: 4 print("VFR flight conditions.") 5 elif visibility >= 3: 6 print("Marginal VFR conditions.") 7 else: 8 print("IFR conditions — instrument flight rules apply.") Does this script output the correct flight category?
