Tokyo to New York (RJTT–KJFK): Long-Haul Cruise and Fuel Briefing
The Tokyo Haneda (RJTT) to New York Kennedy (KJFK) sector is one of the ultimate flight simulator endurance tests: oceanic and Arctic routing, multiple FIR crossings, and nearly thirteen hours airborne in a wide-body. NG ROUTE builds the airway structure automatically so you can focus on fuel, cruise level, and export instead of hand-picking fixes across the Pacific.

Recommended settings:
- Airway level: HIGH
- Aircraft: Boeing 777-300ER, Boeing 787-9, or Airbus A350-900
Distance comes back near 6,079 NM — far longer than a map straight line because the path follows published long-haul structure through northern Pacific and North American entry fixes.
Understanding the route string
Long-haul ICAO strings look intimidating. A sample from NG ROUTE begins:
RJTT DCT INUBO Y804 LALID … Q140 KODEY DCT HNK … DCT KJFK
You will see Japanese Y airways, trans-Pacific R and A routes, North American jet airways (J, Q), and several DCT oceanic connectors. Do not type this manually — export the FMS or PLN file and verify fixes in batches of ten during preflight.
The nav log is your briefing bible. Scroll it before fueling; note coast-in fixes where ETOPS-style awareness matters in roleplay sessions.
Great circle and map distortion
On the NG ROUTE Mercator map, the route curves toward higher latitudes — a normal great-circle tendency on long eastbound northern routes. The curve is not a routing error. Read our great circle article for why the longest jobs look bent online.
Cruise altitude
NG ROUTE suggests upper thirties for this distance — typically FL390 on eastbound-style tracks with semi-circular conventions. Actual oceanic clearances may differ on VATSIM; file NG ROUTE's suggestion initially.
Consider a step climb after burn-off in the sim: many airlines climb from FL350 to FL390 mid-route as weight decreases. NG ROUTE shows one nominal cruise for planning simplicity.
Fuel planning (B777-300ER example)
| Component | Approximate magnitude |
|---|---|
| Block time | ~12 h 25 min at 490 kt TAS |
| Trip fuel | ~105 t (see NG ROUTE panel) |
| Contingency + alternate + reserve | +12–15 t combined |
| Total fuel to load | ~117–120 t |
Select B777-300ER in NG ROUTE for tailored burn. An A350-900 shows lower trip fuel (~75–80 t trip) thanks to 5,800 kg/h cruise burn in the planner model — always use the aircraft you will actually fly.
Load TOTAL FUEL in the sim payload screen. Running dry over the Pacific is not where you want to discover a math error.
Winds and ETA sensitivity
Open the wind aloft chart below the map. Pacific entry and Atlantic exit legs dominate ETA swing. Strong headwinds on the Q and J route segments can add thirty-plus minutes; tailwinds do the opposite. Rebuild the plan on flight day for fresh winds if you are serious about schedule roleplay.
METAR at departure and arrival
RJTT METAR sets Tokyo runway and departure QNH. KJFK METAR drives arrival expectation — four runway families and crosswind awareness on 31L/R vs 13L/R. Live MSFS weather makes this briefing relevant; see live weather matching guide.
SIGMET along track
Winter routes may flag turbulence or icing SIGMETs across the Pacific or over Canada. Summer convective SIGMETs appear near the US east coast coast-in. NG ROUTE highlights intersecting bulletins — review the SIGMET guide for interpretation.
Export and cockpit workflow
- Build plan, save fuel screenshot or note TOTAL.
- Export .FMS / .PLN / mission file.
- Load in FMS before pushback at Haneda.
- Verify first oceanic fix matches nav log row ~5–8.
- Monitor T/C and T/D markers — see T/C and T/D guide.
Session tips
- Use time acceleration only after cruise stable if you lack real-world hours.
- Pause for meal breaks but keep fuel and step-climb discipline.
- Practice one coast-in STAR at KJFK for arrival realism.
- File on VATSIM only if you can commit to the full block — controllers appreciate honesty about endurance.
RJTT–KJFK is NG ROUTE at full scale: thousands of nautical miles, real airway names, live METAR bookends, and exportable professional structure. Treat it as a capstone flight after mastering shorter European sectors like LFPG–EHAM.
Long-haul fuel figures are simulation estimates. AIRAC routing changes may alter fix names between cycles.
