On a VFR-on-top clearance, you must remain on which flight plan?

• A. Remain on an IFR flight plan
• B. Cancel IFR and fly VFR
• C. File a DVFR plan
• D. No plan required

Answer: (A)

When ATC issues a VFR-on-top clearance, you’re still operating under an IFR clearance. The thing that stays in effect is the IFR flight plan, so you must remain on an IFR flight plan (not cancel it) unless you explicitly cancel IFR. This arrangement lets ATC provide routing and separation under IFR while you fly VFR on top of the weather layer. You could cancel IFR and fly purely VFR later, but that would end the VFR-on-top situation and the IFR clearance; DVFR isn’t required here, and no plan would not reflect the continued IFR clearance.
