What type of flight plan is required if you exit the ADIZ on the coast?

The correct response is that a DVFR, or Defense VFR flight plan, is required when exiting the Air Defense Identification Zone (ADIZ) along the coast. A DVFR flight plan is specifically designed for pilots flying under Visual Flight Rules (VFR) who intend to operate in or near the ADIZ. This type of flight plan provides the necessary information to air traffic control (ATC) to ensure the safety and security of the airspace, especially in sensitive areas like those adjacent to coastal regions.

When operating in an ADIZ, pilots must communicate their intentions and movements to ATC. By filing a DVFR flight plan, the pilot ensures they are monitored while providing important operational details such as the route of flight and the expected communication with ATC. This is vital for maintaining the integrity of airspace security and facilitating the identification of aircraft, thereby allowing for a better management of potential national defense actions.

In contrast, the other types of flight plans have specific uses that do not align with exiting an ADIZ. An IFR flight plan is for instrument flight rules, used in controlled airspace primarily for aircraft operating on instruments. A standard VFR flight plan is suitable for general flying but does not meet the specific requirements when exiting an ADIZ
