When is an IFR clearance required during VFR weather conditions?
A
When operating in the Class E airspace.
B
When operating in a Class A airspace.✓ Correct Answer
C
When operating in airspace above 14,500 feet.
Explanation
Under 14 CFR 91.135, every operation in Class A airspace (18,000 feet MSL up to FL600) must be conducted under IFR on an ATC clearance received before entering, whatever the weather. VFR flight is permitted in Class E airspace and above 14,500 feet MSL below Class A, so an IFR clearance is not required there in VFR conditions.
