Question on fuel consumption
The government routinely publishes a list of miles-per-gallon
consumption ratings for all cars sold in the U.S. Does anyone know whether such a list exists for aviation? I'm looking for a list of fuel consumption ratings for: - private jets - commercial jets. ....AND, if such a list exists, a per-passenger fuel consumption by type of aircraft. I thank you in advance for your answers... |

It's true that with a 20-knot wind the outbound journey will take a bit longer than the return. (20-knot winds hereabouts almost always come from the NNW, which is where I am generally going.) all the best -- Dan Ford email: (put Cubdriver in subject line) Warbird's Forum www.warbirdforum.com Piper Cub Forum www.pipercubforum.com the blog www.danford.net |

"Shemp McGurk" wrote in message om... Does anyone know whether such a list exists for aviation? Nope. Too many variables. Winds, air temperature, and payload all affect this pretty significantly, particularly in jets. Not to mention the huge variety of airframe/engine combos out there. I'm looking for a list of fuel consumption ratings for: - private jets - commercial jets. ...AND, if such a list exists, a per-passenger fuel consumption by type of aircraft. I thank you in advance for your answers... If you don't need a precise number, look at the aircraft's range with maximum fuel and its fuel capacity. You can get this from the manufacturers' websites. Jets typically think about fuel consumption in pounds, so keep in mind there are about 6 pounds of Jet-A to the gallon. Regarding weight, there are a few numbers you can look at: MGTOW (max gross takeoff weight), empty weight, and "payload with full fuel." If they don't list how much fuel it carries for maximum range, look at the weights. Generally speaking, fuel weight will equal MGTOW minus empty weight minus full fuel payload. FYI, I once ballparked a Gulfstream V's fuel consumption as something like 1 gallon per mile, and a 747-400's as 6 gallons per mile. If there's a specific scenario you're trying to examine (i.e. Learjet versus Hummer H2) I suggest asking that question specifically. Odds are someone here will be able to provide far more precise numbers than I could. Also, you might try calling a local jet charter operator. They can surely give you numbers for the planes they operate. Best, -cwk. |

Avgas is 6 pounds, but I think Jet Fuel is 6.5 http://www.fs.fed.us/im/directives/f...5709.16_30.txt |

Actually, your Gulfstream V comparison with the 747-400 is exactly the kind of thing I'm looking for: the per-passenger miles-per-gallon on a private jet versus the per-passenger miles-per-gallon on a commercial jet. And from the example you give above, it's about what I thought it would be: a 747 with, say, 300 passengers is consuming 6 gallons per mile and a Gulfstream with, say, 10 passengers is consuming 1 gallon per mile, the per-passenger miles-per-gallon is WAY higher with the private jet than with the commercial jet. Yes? Also, you might try calling a local jet charter operator. They can surely give you numbers for the planes they operate. Best, -cwk. |
