Finding Helicopter Fuel Burn Rates

[girafabear]

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?

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,

On the AS350B2, we use 40gal/hr or about 200 liter/hour. (About 1 drum.)

Okay.....multiply that X 13, and you come up with a "cranes" fuel consumption !! :shock:

 

As said, "personal experience"!

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.

Thanks very much everyone! I'll be sure to take a look into the engine manuals, and start building up that personal experience.

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

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.

- 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.
