Robbie Driver Posted June 13, 2003 Report Share Posted June 13, 2003 Good evening, Any R44 pilots and/or operators would you mind sharing your fuel burn in the aircraft. I usually get approx. 12-13 GPH. RD Quote Link to comment Share on other sites More sharing options...
HeliFrank Posted June 14, 2003 Report Share Posted June 14, 2003 If I remember correctly ours were somewhere around 40 liters/hour unless you don't tighten the the fuel tank cap.Then the average fuel consumption goes up to somewhere around 100 liters per hour Frank (1 US gal = 3,78 Liter), (1 GB gal = 4,54 Liter) Quote Link to comment Share on other sites More sharing options...
HH60Pilot Posted November 12, 2005 Report Share Posted November 12, 2005 We're burning 11-12 gph pulling 17-18" flying at altitude around Lake Tahoe with 3-4 people on board. Doug Quote Link to comment Share on other sites More sharing options...
zippiesdrainage Posted July 19, 2012 Report Share Posted July 19, 2012 Just found this very old topic and felt it need to be ressurected due to the fact that I think it's an important topic. I have never seen an R44 burn 11-12 gal/hour. Even the Robinson website it says the R44 Raven 2 burns 14GPH and the Raven 1 burns 16. We teach our students 18gph and now I'm wondering where the number 18 came from in the first place. Anyway input, ideas, complaints and rants please Quote Link to comment Share on other sites More sharing options...

I am usually pulling near max power on take off (less than 2 min), cruising at 21-22 inches (which is about 100-105 knots, depending on load) and I hold a lot of speed until very short final. My fuel planning seems to be on the nose using 15. I would guess cruising might be near 14 gallons and max power probably closer to 18-19. Really a lot depends on what you are using the ship for and obviously how much power you are pulling. Running 4 minute tours uses a lot more power and fuel than a 30 minute tour where I get to cruise for a bit. I think 18 for a Raven or Clipper 2 gives you a safety factor obviously. The older Raven 1's do use a lot more fuel, as the blade is less efficient as is the carb vs fuel injection.

Anyway input, ideas, complaints and rants please I haven't flown an R-44 but I noticed something the other day in my manual that you don't hear much about. Fuel burn, at least in a turbine engine (and i think in all engines) gets quite a bit more efficient at high altitude. In my aircraft the difference between a fuel burn at 10,000 is 15% less than at sea level. Temperature also affects it (colder, better fuel burn) though it's barely noticeable. Anyway, so somebody who operates in a high altitude environment all the time could see a much better rate. Quote Link to comment Share on other sites More sharing options...
