(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.

5. 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 serviceable. 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 4-6.
 Indicate Area Navigation (RNAV) capability by filing one or more of the codes in TBL 4-7.

1. SBAS " Space-Based Augmentation System
GBAS - Ground-Based Augmentation System
2. No PBN/ code needs to be filed to indicate the ability to fly point-to-point routes using GNSS or INS.
3. Filing one of these four area navigation capabilities as shown does not indicate performance based navigation sufficient
for flying Q-Routes, T-Routes, or RNAV SIDs or STARs. To qualify for these routes, see the section on Performance Based
Navigation Routes.
