Hi All,
Our company Duke, a B60 model, gives cruise fuel flows in the order of 180 L/hr.
That is the figure around about which all the pilots end up establishing, for power settings around 31 inches at 2500 RPM. Various "techniques" are used for leaning the mixture. The achieved TAS is about 180 kts at FL130.
The book figures are considerably lower, by around 30%. For the typical power settings we use, the book says 130 - 140 L/hr.
Some research (via the Net), has uncovered a few other Duke pilots that get virtually the same, high fuel flows.
Other research, though, has suggested that some do seem to get the book figures.
Please can Duke operators post what fuel flows they get.
Thanks very much,
Tom Atkinson
