Appendix 4. FAA Form 7233-4 - International Flight Plan

1. The FAA will accept a flight plan in international format for IFR, VFR, SFRA, and DVFR flights. File the flight plan electronically via a Flight Service Station (FSS), FAA contracted flight plan filing service, or other commercial flight plan filing service. Depending on the filing service chosen, the method of entering data may be different but the information required is generally the same.
2. The international flight plan format is mandatory for:
   1. Any flight plan filed through a FSS or FAA contracted flight plan filing service; with the exception of Department of Defense flight plans and civilian stereo route flight plans, which can still be filed using the format prescribed in FAA Form 7233-1.

      NOTE-
      DoD Form DD-175 and FAA Form 7233-1 are considered to follow the same format.

   2. Any flight that will depart U.S. domestic airspace. For DoD flight plan purposes, offshore Warning Areas may use FAA Form 7233-1 or military equivalent.
   3. Any flight requesting routing that requires Performance Based Navigation.
   4. Any flight requesting services that require filing of capabilities only supported in the international flight plan format.
3. Flight Plan Contents
   1. A flight plan will include information shown below:
      1. Flight Specific Information (TBL 4-1)
      2. Aircraft Specific Information (TBL 4-19)
      3. Flight Routing Information (TBL 4-20)
      4. Flight Specific Supplementary Information (Item 19)
   2. The tables indicate where the information is located in the international flight plan format, the information required for U.S. domestic flights, and the location of equivalent information in the domestic flight plan format.
   3. International flights, including those that temporarily leave domestic U.S. airspace and return, require all applicable information in the international flight plan. Additional information can be found in ICAO Doc. 4444 (Procedures for Air Navigation Services, Air Traffic Management), and ICAO Doc. 7030 (Regional Supplemental Procedures) as well as the Aeronautical Information Publications (AIPs), Aeronautical Information Circulars (AICs), and NOTAMs of applicable other countries.

       NOTE-
       1. PBN Codes B1-B6 indicates RNAV 5 capability. The FAA considers these B codes to be synonymous and qualifying for point-to-point routing but not for assignment to the PBN routes shown in the table.

   15. Combinations of alphanumeric characters not included above are reserved.
   16. The PBN/ specifications are allowed per ICAO Doc. 4444. The FAA makes use of a subset of these codes as described in the section on filing navigation capability.
       3. The following sections detail what capabilities need to be provided to obtain services from the FAA for:

          • IFR flights (general).

          • Assignment of Performance-Based Navigation (PBN) routes.

          • Automated Departure clearance (via Datacom DCL or PDC).

          • Reduced Vertical Separation Minima (if requesting FL 290 or above).

          • Reduced Separation in Oceanic Airspace.

       4. Capabilities such as voice communications, required communications performance, approach aids, and ADS-C, are not required in a flight plan that remains entirely within domestic airspace.
       5. 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.
       6. 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.

   17. 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.
       1. 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.

       2. 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.

          NOTE-
          1. SBAS – Space-Based Augmentation System
          GBAS - Ground-Based Augmentation System

   18. No PBN/ code needs to be filed to indicate the ability to fly point-to-point routes using GNSS or INS.
   19. 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.

       (c) Transponder Capabilities (Item 10b)

       • For domestic flights, it is not necessary to indicate Mode S capability. It is acceptable to simply file one of the following codes in TBL 4-8.

       TBL 4-8
       Mode C

       Capability	Item 10b
       Transponder with no Mode C	A

   21. Automated Departure Clearance Delivery (DCL or PDC). When planning to use automated pre-departure clearance delivery capability, file as indicated below.
       1. PDC provides pre-departure clearances from the FAA to the operator's designated flight operations center, which then delivers the clearance to the pilot by various means. Use of PDC does not require any special flight plan entry.
       2. DCL provides pre-departure clearances from the FAA directly to the cockpit/FMS via Controller Pilot Datalink Communications (CPDLC). Use of DCL requires flight plan entries as follows:

          • Include CPDLC codes in Item 10a only if the flight is capable of en route/oceanic CPDLC, the codes are not required for DCL.

          • Include Z in Item 10a to indicate there is information provided in Item 18 DAT/.

          • Include the clearance delivery methods of which the flight is capable, and order of preference in Item 18 DAT/. (See AIM 5-2-2)

          ○ VOICE - deliver clearance via Voice

          ○ PDC - deliver clearance via PDC

          ○ FANS - deliver clearance via FANS 1/A

          ○ FANSP - deliver clearance via FANS 1/A+

   22. Operating in Reduced Vertical Separation Minima (RVSM) Airspace (Item 10a). When planning to fly in RVSM airspace (FL 290 up to and including FL 410) then file as indicated below.
       1. If capable and approved for RVSM operations, per AIM 4-6-1, Applicability and RVSM Mandate (Date/Time and Area), file a W in Item 10a. Include the aircraft registration mark in Item 18 REG/, which is used to post-operationally monitor the safety of RVSM operations.

          • Do not file a “W” in Item 10a if the aircraft is capable of RVSM operations, but is not approved to operate in RVSM airspace.

          • If RVSM capability is lost after the flight plan is filed, request that ATC remove the 'W' from Item 10a.

       2. When requesting to operate non-RVSM in RVSM airspace, using one of the exceptions identified in AIM 4-6-10, do not include a “W” in Item 10a. Include STS/NONRVSM in Item 18. STS/NONRVSM is used only as part of a request to operate non-RVSM in RVSM airspace.

          Estimated Elapsed Times	Item 18 EET/	Include when filing flight plan with center other than departure center	N/A

4. Instructions for Flight Routing Items

   1. Departure Airport (Item 13, Item 18 DEP/)

   2. Departure Time (Item 13)

      Indicate the expected departure time using 4 digits, 2 digits for hours and 2 digits for minutes. Time is to be entered as Coordinated Universal Time (UTC).

      3. Requested Cruising Speed (Item 15)

      1. Include the requested cruising speed as True Airspeed in knots using an N followed by four digits.
      2. Indicate the requested cruising speed in Mach using an M followed by three digits.
   3. Requested Cruising Altitude or Flight Level (Item 15)
      1. Indicate a Requested Flight Level using the letter F followed by 3 digits.
      2. Indicate a Requested Altitude in hundreds of feet using the letter A followed by 3 digits.
   4. Route (Item 15)

      Provide the requested route of flight using a combination of published routes, latitude/longitude, and/or fixes in the following formats.

      1. Consecutive fixes, lat/long points, NAVAIDs, and waypoints should be separated by the characters “DCT”, meaning direct.
      2. A published route should be preceded by a fix that is published on the route, indicating where the route will be joined. The published route should be followed by a fix that is published as part of the route, indicating where the route will be exited.
      3. It is acceptable to specify intended speed and altitude changes along the route by appending an oblique stroke followed by the next speed and altitude. However, note that FAA ATC systems will neither process this information nor display it to ATC personnel. Pilots are expected to maintain the last assigned altitude and request revised altitude clearances from ATC.

         6. Delay En Route (Item 15, Item 18 DLE/)

      4. ICAO defines Item 18 DLE/ to provide information about a delay en route. International flights with a delay outside U.S. domestic airspace should indicate the place and duration of the delay in Item 18 DLE/. The delay is expressed by a fix identifier followed by the duration in hours (H) and minutes (M), HHMM.
      5. U.S. ATC systems will accept but not process information in DLE/. Therefore, for flights in the lower 48 states, it is preferable to include the delay as part of the route (Item 15). Delay in this format is specified by an oblique stroke (/) followed by the letter D, followed by 2 digits for hours (H) of delay, followed by a plus sign (+), followed by 2 digits for minutes (M) of delay: /DHH+MM.
   5. Destination Airport (Item 16, Item 18 DEST/)
      1. Enter the destination airport. The airport should be identified using the four-letter location identifier accessible through FAA Order JO 7350.9, Location Identifiers, or from ICAO Document 7910. FSS and FAA contracted flight plan filing services will allow up to 11 characters in the destination field. This will permit entry of non-ICAO identifier airports, and other fixes such as an intersection, fix/radial/distance, and latitude/longitude coordinates. Other electronic filing services may require a different format.
      2. When the intended destination (Item 16) is outside of domestic U.S. airspace, or if using the paper version of FAA Form 7233-4, or if the chosen flight plan filing service does not allow non-ICAO airport identifiers in Item 13 or Item 16, use the following ICAO procedure. Enter four Z's (ZZZZ) in Item 13 and include the non-ICAO airport location identifier, fix, or waypoint location in Item 18 DEP/. A text description following the location identifier is permissible in Item 18 DEP/.

         8. Total Estimated Elapsed Time (Item 16)

         All flight plans must include the total estimated elapsed time from departure to destination in hours (H) and minutes (M), format HHMM.

         9. Alternate Airport (Item 16, Item 18 ALTN/)

      3. When necessary, specify an alternate airport in Item 16 using the four-letter location identifier from FAA Order 7350.9 or ICAO Document 7910. When the airport does not have a four-letter location identifier, include ZZZZ in Item 16c and file the non-standard identifier in Item 18 ALTN/. 
      4. While the FAA does not require filing of alternate airports in the flight plan provided to ATC, rules for establishing alternate airports must be followed.
      5. Adding an alternate may assist during Search and Rescue by identifying additional areas to search.
      6. Although alternate airport information filed in a flight plan will be accepted by air traffic computer systems, it will not be presented to controllers. If diversion to an alternate airport becomes necessary, pilots are expected to notify ATC and request an amended clearance.

         10. Estimated Elapsed Times (EET) at boundaries or reporting points (Item 18 EET/)

         EETs are required for international or oceanic flights when crossing a Flight Information Region (FIR) boundary. The EET will include the ICAO four-letter location identifier for the FIR followed by the elapsed time to the FIR boundary (e.g., KZNY0245 indicates 2 hours, 45 minutes from departure until the New York FIR boundary).

         11. Remarks (Item 18 RMK/)

         Enter only those remarks pertinent to ATC or to the clarification of other flight plan information. Items of a personal nature are not accepted.

         NOTE-
         1. “DVRSN” should be placed in Item 11 only if the pilot/company is requesting priority handling to their original destination from ATC as a result of a diversion as defined in the Pilot/Controller Glossary.

   6. Do not assume that remarks will be automatically transmitted to every controller. Specific ATC or en route requests should be made directly to the appropriate controller.

      g. Flight Specific Supplemental Information (Item 19)

   7. Item 19 data must be included when completing FAA Form 7233-4. This information will be retained by the facility/organization that transmits the flight plan to Air Traffic Control (ATC), for Search and Rescue purposes, but it will not be transmitted to ATC as part of the flight plan.
   8. Do not include Supplemental Information as part of Item 18. The information in Item 19 is retained with the flight plan filing service for retrieval only if necessary.
   9. Minimum required Item 19 entries for a domestic flight are Endurance, Persons on Board, Pilot Name and Contact Information, and Color of Aircraft. Additional entries may be required by foreign air traffic services, or at pilot discretion.
      1. After E/ Enter fuel endurance time in hours and minutes.
      2. After P/ Enter total number of persons on board using up to 30 alphanumeric characters. Enter TBN (to be notified) if the total number of persons is not known at the time of filing.
      3. R/ (Radio) Cross out items not carried
      4. S/ (Survival Equipment) Cross out items not carried.
      5. J/ (Jackets) Cross out items not carried.
      6. D/ (Life Raft/Dinghies) Enter number carried and total capacity. Indicate if covered and color.
      7. A/ (Aircraft Color and Markings) Enter aircraft color(s).
   10. N/ (Remarks. Not for ATC) select N if no remarks. Enter comments concerning survival equipment and information concerning personal GPS locating service, if utilized. Enter name and contact information for responsible party to verify VFR arrival/closure, if desired. Ensure party will be available for contact at ETA. (for example; FBO is open at ETA)
   11. C/ (Pilot) Enter name and contact information, including telephone number, of pilot-in-command. Ensure contact information will be valid at ETA in case SAR is necessary.
