All clock times are in four figures, UTC.
All estimated elapsed times are in four figures (hours and minutes).
Area preceding Item 3 is to be completed by ATS and COM services.
If called upon to fill out an International Flight Plan you may wish to copy the filed flight plan portion of your computer flight plan as a guide.

For A Gulfstream G450 with enhanced navigation (Certification F-Enhanced): SBDE2E3FGHIJ3J5M1RWXYZ/HB1D1
13. Departure Aerodrome.
The four letter location identifier of the departure airport, or “ZZZZ” if no identifier (then specify airport in Item 18 with “DEP/” followed by name).
15. Speed. Cruising Speed. Enter the “N” followed by four figures to specify true airspeed in knots (e.g., “N0485”), or “M” followed by three figures to specify true Mach Number (e.g., “M083”)
Cruising Level. Enter “F” followed by three figures to specify a flight level (e.g., “F450”), or “A” followed by three figures to specify altitude in hundreds of feet (e.g., “A100”)
Route. Flights along designated ATS routes. Insert the route designator if the departure airport is located on the route, otherwise insert “DCT” followed by the point of joining the first ATS route, followed by the designator of the route. Then, insert each point at which either a change of speed or level, a change of ATS route, and/or a change of flight rules is planned. Followed in each case by the designator of the next route segment, even if same as the previous one, or by “DCT” if the next point will be outside a designated route, unless both points are specified by geographic coordinates.
Flights outside designated ATS routes. Insert points normally not more than 30 minutes flying time or 200 nm apart, including each point at which a change of speed or level, a change of track, or a change of flight rules is planned. Insert “DCT” between successive points unless both points are defined by geographic coordinates or by bearing and distance.
ATS routes. The coded designator (2 to 7 characters), i.e., “UB10”.
Significant points. The coded designator (2 to 5 characters) of the assigned point, i.e., “HADDY”. Degrees only (7 characters) will be two figures describing latitude in degrees followed by “N” or “S” and three figures describing longitude in degrees followed by “E” or “W”, i.e., “46N078W”. Degrees and minutes (11 characters) will be four figures describing latitude in degrees and minutes followed by “N” or “S” and five figures describing longitude in degrees and minutes followed by “E” or “W”, i.e., “4620N07805W”. Bearing and distance from a navigation aid will be described by two or three characters, then the bearing in three figures (degrees magnetic), then the distance in three figures (nautical miles), i.e., “DUB180040”.
Change of speed or level (maximum 21 characters). The point at which a change of speed (5% TAS or 0.01 Mach or more) or a change of level is planned will be followed by an oblique stroke and both the cruising speed and cruising level without a space. I.e., “DUB180040/M082F330”.
16. Destination Aerodrome. The four letter ICAO location identifier or “ZZZZ” if no identifier (then specify airport in Item 18 with “DEST/” followed by name).
Total Elapsed Time. In four digits (hours and minutes).
Alternate Aerodrome. The four letter ICAO location identifier or “ZZZZ” if no identifier (then specify airport in Item 18 with “ALTN/” followed by name).
18. Other Information. As necessary.
- “EET/” (Significant points or FIR boundary designators and accumulated estimated elapsed time to such points.)
- “REG/” (Registration markings of the aircraft, if different from Item 7 aircraft identification.)
- “SEL/” (SELCAL code)
- “OPR/” (Name of operator, if not obvious from Item 7.)
- "NAV" Codes
- RNV RNAV
- A1 RNAV 1 arrival procedures
- D1 RNAV 1 departure procedures
- E2 RNAV 2 routes
- LPV LPV approach
- "PBN/" Performance Based Navigation codes:
- A1 RNAV 10, RNP 10
- B1 RNAV 5 via all permitted sensors (this wasn't in the cited ICAO doc but has been added since)
- B2 RNAV 5 via GNSS
- B3 RNAV 5 via DME/DME
- B4 RNAV 5 via VOR/DME
- C1 RNAV 2 via all permitted sensors
- D1 RNAV 1 via all permitted sensors
- L1 RNP 4 operations permitted

- S2 GNSS Approach using Baro-VNAV
- T1 RNP AR Approach authorized
- S Datalink via SATCOM
- V Datalink via VHF
- “RMK/” (plain language remark.)
For A Gulfstream G450 with advanced NAV: RNVD1E2A1
For A Gulfstream G450 with advanced PBN: B1C1D1L1O1S2
This used to specify the following, but the requirement has since been deprecated.
For A Gulfstream G450 with advanced NAV the answer had been: DAT/SV, but that has since been deprecated. (You don't need it anymore.)
The Gulfstream manuals say to add "RMK/AGCS EQUIPPED" here but you should not do that in a G450/G550 because it will prevent your "Acknowledge" reply.

Gulfstream G450 Solution
Supplementary Information. Endurance. Four figures (hours and minutes) of fuel on board.
Persons on Board.
Emergency and survival equipment. Cross out those items not carried.
The Gulfstream solution is available here: Gulfstream Flight Plan Codes, but this solution is a bit dated.
