When is a flight plan required for IFR operations?

• A. When operating under IFR in controlled airspace or in weather requiring IFR; a flight plan is required for IFR flight.
• B. Only on international flights.
• C. Never required.
• D. Only for VFR.

Answer: (A)

When you fly under instrument flight rules, a flight plan is required so ATC can provide proper separation and safely manage your route. Filing the plan before departure tells ATC where you’re going, what altitude you’ll fly, and your expected times, allowing them to issue an IFR clearance and sequence you with other traffic. This requirement applies in controlled airspace or whenever weather conditions require IFR rather than VFR, ensuring you’re adequately coordinated even if conditions degrade. The other options don’t fit because IFR flight plans are not limited to international flights, they’re not optional, and IFR is not the same as VFR.
