background image (e) Flights that leave domestic United States airspace may be required to include additional capabilities, per requirements for the FIRs being overflown. Consult the appropriate State Aeronautical Information Publications for requirements. (f) Include the capability only if: The requisite equipment is installed and operational; The crew is trained as required; and Any required Operations Specification, Letter of Authorization, or other approvals are in hand. NOTE - Do not include a capability solely based on the installed equipment if an operational approval is required. For exam- ple, all U.S. civil operators require either Operations Specification, Management Specification, or Letter of Authorization B036, as applicable, in order to include NAV/M2 (RNP 2 (oceanic/remote)), PBN/A1 (RNAV 10 (RNP 10)), or PBN/L1 (RNP 4) in Item 18. Filing equipment and capability in an IFR Flight Plan. This section details the minimum requirements to identify capabilities in an IFR flight plan for flights in the domestic United States. Other requirements to file a capability are associated with obtaining specific services as described in subsequent sections. The basic capabilities that must be addressed include Navigation, Transponder, Voice, and ADS - B Out as described below. A designator for "Standard" capability is also allowed to cover a suite of commonly carried voice, navigation, and approach equipment with one code. (a) Standard Capability and No Capability (Item 10a) Use "S" if VHF radio, VOR, and ILS equipment for the route to be flown are carried and service- able. Use of the 'S' removes the need to list these three capabilities separately. Use "N" if no communications, navigation, or approach aid equipment for the route to be flown are carried or the equipment is unserviceable. When there is no transponder, ADS - B, or ADS - C capability then file only the letter 'N' in Item 10b. (b) Navigation Capabilities (Item 10a, Item 18 NAV/) Indicate radio navigation capability by filing one or more of the codes in TBL 4 - Indicate Area Navigation (RNAV) capability by filing one or more of the codes in TBL 4 - TBL 4 - Radio Navigation Capabilities Capability Item 10a Item 18 NAV/ VOR DME TACAN TBL 4 - Area Navigation Capabilities Capability Item 10a Item 18 NAV/ GNSS SBAS (if WAAS equipped) GBAS (if LAAS equipped) INS DME / DME DR VOR / DME DOR NOTE - SBAS - Space - Based Augmentation System GBAS - Ground - Based Augmentation System Appendix 4 - FAA Form 7233 - - International Flight Plan
