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

The correct choice is DVFR, which stands for Defense VFR. This type of flight plan is specifically required when operating in or near Air Defense Identification Zones (ADIZ). The purpose of the DVFR flight plan is to provide information to the authorities about your flight route and intentions, especially when exiting an ADIZ.

When a pilot leaves an ADIZ, filing a DVFR ensures that appropriate air traffic control is aware of the flight's exit from controlled airspace, which is critical for maintaining security and coordination with military operations in the area. The DVFR provides situational awareness for both the pilot and the authorities, enabling effective management of airspace and enhancing safety.

Other types of flight plans, such as VFR (Visual Flight Rules) and IFR (Instrument Flight Rules), govern general flight operations but do not specifically pertain to exiting an ADIZ. SVFR (Special VFR) applies to operations that require clearance to fly in controlled airspace under visual conditions during specific circumstances, but it is not related to the unique requirements of exiting an ADIZ. Thus, the requirement for a DVFR flight plan becomes essential in such a scenario.
