What does a DVFR flight plan allow a pilot to do?

A DVFR (Defense VFR) flight plan specifically allows a pilot to cross an Air Defense Identification Zone (ADIZ). An ADIZ is a designated area surrounding a country, where aircraft must comply with specific identification requirements to enhance national security. Filing a DVFR flight plan notifies air traffic control and defense agencies of the pilot's intentions and flight details, thus providing a method for the aircraft to cross these critical areas legally and safely.

This process is significant not only for ensuring situational awareness for air traffic controllers but also for augmenting national defense mechanisms, especially in regions where security concerns are heightened. The DVFR flight plan distinctly facilitates the necessary communication and identification protocols required in these sensitive airspaces, making it essential for pilots who need to travel through an ADIZ.

Options involving landing without a flight plan, flying VFR at night, or entering controlled airspace do not directly relate to the primary function of a DVFR flight plan, which focuses specifically on the requirements around the ADIZ.
