What must you do to correctly file a composite flight plan?

To correctly file a composite flight plan, it is necessary to check both the VFR and IFR boxes on the flight plan form. A composite flight plan is unique in that it allows the pilot to transition from Visual Flight Rules (VFR) to Instrument Flight Rules (IFR) during the flight, typically when entering controlled airspace or when conditions necessitate IFR operations. By checking both boxes, you inform air traffic control (ATC) and any necessary parties that the flight will initially operate under VFR conditions but may switch to IFR as the flight progresses.

This is vital for proper coordination with ATC, ensuring that they are aware of the flight’s operational intentions and can provide the necessary services for both VFR and IFR portions of the flight. This level of detail helps maintain safety and efficiency in the airspace system, allowing for seamless handoffs between VFR and IFR operations.
