Flight Plan Filing Updates
International flight plan updates
- December 2015 – The FAA has published additional guidance on Filing for Advanced Surveillance Broadcast Capability (PDF) in an FAA ICAO Flight Plan. Guidance is included for both Field 10b and Field 18 ("SUR/" and "CODE/"). The AIM also provides guidance on filing for Advanced Surveillance Broadcast (ADS-B).
International (ICAO) Flight Plan Filing
Criteria for use
The FAA prefers users to file ICAO format flight plans for all flights. An ICAO format flight plan MUST be used when:
- The flight will enter international airspace, including oceanic airspace controlled by FAA facilities.
- The flight expects routing or separation based on Performance Based Navigation (PBN), e.g. RNAV 1.
- The flight will enter RVSM airspace.
- The flight expects services based on ADS-B.
How to prepare your international flight plan form
- Use FAA Form 7233-4 – Information needed when filing this form is described in Aeronautical Information Manual (AIM) Section 1, Paragraph 5-1-9.
- You will need to provide certain information, such as:
- aircraft identification
- special equipment
- departure/arrival points
- cruising altitude
- route of flight
- Review additional guidance as appropriate:
- Aircraft type designators – Please consult ICAO Document 8643 before providing your approved 24-character aircraft type to avoid rejection of your flight plan.
- Performance Based Navigation – Operational approvals (Op Specs\MSpec\Part 91 LOA) are required for many Performance Based Navigation operations. You can find guidance on required approvals and which codes to file for various PBN capabilities in this Operational Approval Guidance Table (PDF, 196 KB). If you have any trouble with filing PBN capability, consult this file for useful tips.
- Items 10 and 18 changed in November 2012 – This brochure (PDF, 181 KB) provides an overview of the content requirements for each item in the flight plan, including all the items that changed in November 2012.
- Domestic filers – If you are flying only in the domestic United States, without entering international or oceanic airspace you can follow these tips (PDF) and simplify your flight plan and remove data not required by the FAA.
Previous international flight plan updates
- November 2013 – FAA Systems no longer require use of NAV/ information to convey PBN/ capability; indicating PBN capability in the PBN/ indicator is sufficient. For more information, refer to Filing Performance Based Navigation Capability in an FAA Domestic ICAO Flight Plan (PDF).
- You can still file NAV/ information in addition to the PBN/ information if desired. Including the NAV/ information can permit you to request PBN procedures for only the departure, en route, or arrival phase. If you elect to provide the NAV/ information, you must include "Z" in Item 10 of the FAA ICAO Flight Plan.
- November 2013 – Also, note that the systems now enforce the rule that PBN/ information must be included when an "R" is filed in ICAO Field 10.
Domestic Flight Plan Filing
Criteria for use
Flights that remain wholly within domestic United States airspace, and do not meet any of the criteria requiring an ICAO format flight plan, may use an FAA domestic format flight plan.
How to prepare your domestic flight plan
You may choose one of the following options:
Previous domestic flight plan updates
- Domestic equipment suffixes changed in October 2013. The currently published AIM contains the updated suffixes.
How to file your flight plan (domestic or international)
- Submit a hardcopy flight plan form to your local flight service station.
- Call Flight Services (1-800-WX-BRIEF or 1-800-992-7433) – The flight services specialist will file your flight plan.
