In preparing for my “Seven Continent” tour, I’m testing the Longitude’s free mod that fixes many of this aircraft’s issues. I flew an intracontinental route tonight to see if this is a viable aircraft (fuel-wise) to fly to all the continents.
Here are my fuel statistics for a 2,050 nm flight I took tonight between KSNA (John Wayne/Orange Co., California) and KMIA (Miami Int’l). The flight took 4 hours, sixteen minutes. I flew at FL450 with tailwinds around 60 kts and, at times, 78 kts.
Mod’ed Longitude Specs:
- Max Takeoff Weight: 39,500 lbs
- Max Fuel capacity: 14,593 lbs (2,178 gal)
Flight Specs and Notes:
- Actual Weight at takeoff (with just my copilot and I, 400 lbs of baggage, and 100% fuel level): 38,722 lbs (of which 14,593 was fuel weight)
- The consumption figures include taxiing from departure terminal, flying, and taxiing to arrival terminal
- My TAS was 460 during the majority of the flight (cruise phase)
- Flight plan ETE: 04:07
- Actual ETE: 04:16:13 (or 4.27 hrs)
- Fuel level: 6,700 lbs (1000 gal)
- Actual weight at arrival: 30,829 lbs
- Fuel used: 7,893 lbs (1,178 gal)
- Avg fuel per hour (all flight phases): 1,849 lbs/hr or 276 gal/hr
- Avg of fuel per nm (all flight phases): 3.85 lbs/nm 0.58 gals/nm
This flight was the jet stream, as noted by the tailwinds in the introduction and with only two souls on board. This flight was at FL450, which provides increased efficiency compared to lower altitudes.
Base on the above, I can expect to fly 7.0 hours or 3,374 nm (sans a 11% “reserve” or just under an hour’s worth of reserve flight or 417 nm of reserve flight).

For you geeky types, here are more of my fuel statistics on my “Seven Continents of Flight” tour. There is a PDF in the following link. Go to the “seven-continents…” folder. There are also all my flight plans…
