girafabear Posted April 9, 2010 Report Share Posted April 9, 2010 Hi, I'm a new pilot, and I've been wondering where the most dependable information on fuel burn rates can be found. Some PFMs have the charts in the manufacturer's data, but I don't know where else to go when it's missing. Help? Quote Link to comment Share on other sites More sharing options...
dimit Posted April 10, 2010 Report Share Posted April 10, 2010 Hi GB, Here are some numbers I use. Don't know that they're published anywhere... Jet Ranger- 25gals/hr Long Ranger - 250 lbs/hr A-Star BA/B2 - 300 lbs/hr Curious to see what others have to say. Cheers, Dick Quote Link to comment Share on other sites More sharing options...
ray Posted April 10, 2010 Report Share Posted April 10, 2010 On the AS350B2, we use 40gal/hr or about 200 liter/hour. (About 1 drum.) most dependable information on fuel burn rates Personal experience. Quote Link to comment Share on other sites More sharing options...
Helilog56 Posted April 10, 2010 Report Share Posted April 10, 2010 On the AS350B2, we use 40gal/hr or about 200 liter/hour. (About 1 drum.) Personal experience. Okay.....multiply that X 13, and you come up with a "cranes" fuel consumption !! :shock: As said, "personal experience"! Quote Link to comment Share on other sites More sharing options...
Heliian Posted April 10, 2010 Report Share Posted April 10, 2010 If you can look in the engine manufacturers manual, you'll most likely find the fuel burn rates in the description section, these are the bench rates of the engine usually at MCP and are not helicopter specific. Only experience or a flowmeter will give you a better idea. Quote Link to comment Share on other sites More sharing options...
girafabear Posted April 10, 2010 Author Report Share Posted April 10, 2010 Thanks very much everyone! I'll be sure to take a look into the engine manuals, and start building up that personal experience. Quote Link to comment Share on other sites More sharing options...
Amphibious Posted April 10, 2010 Report Share Posted April 10, 2010 R44 I plan around 16gph 206 & 500 I use 26 (they all seem to be a little diff). 30gph makes a nice planning figure is weight isn't an issue, 2min/gallon. then there is my beloved 214B... 680ltr/hr Quote Link to comment Share on other sites More sharing options...
rainman Posted April 10, 2010 Report Share Posted April 10, 2010 212 is kinda neat, if you are pulling 65% torque= generally speaking 650lbs/hr. Just add a zero to the torque and it works out nicely in cruise within reason and barring certain altitude and temp differences of course A119 works out to about 440lbs/hr in cruise. 390ish skiing and bucketing.

canukav8tor Posted April 11, 2010 Report Share Posted April 11, 2010 - 412EP(CH146) -- ~720 lbs/hr at 120-130 kt cruise, ~770 lbs/hr slower with about 10-15% hover work. - BV44 (CH-47) -- ~2300-2400 lbs/hr, low and slow (120) and/or slinging up to 70-80 kts, ~2000-2100 lbs/hr at 10k' and 140-150 kts clean.
