VFR flights (except for DoD and law enforcement flights) into an ADIZ are required to file DVFR flight plans for security purposes. Detailed ADIZ procedures are found in Section 6 , National Security and Interception Procedures, of this chapter.

REFERENCE-

14 CFR part 99, Security Control for Air Traffic.

DVFR flight plans must be filed using FAA Form 7233-4 or DD Form 1801.

Enter the letter “D” in Item 8, Type of Flight, of FAA Form 7233-4 or DD Form 1801.

DVFR flights where pilots decline search and rescue coverage must clearly indicate “NORIV” in Item 18 following the indicator “RMK/.” This flight plan must still be activated in order to properly notify NORAD, however no flight plan cancellation will be expected. EXAMPLE-
