CSU Fuel Flow/Range
Hi all,
Just a quick question.
When in cruise with the engine set up as 24/2400rpm leaned, if the throttle was pushed all the way in to say 27+ inches would the fuel flow increase/stay the same? (provided nothing else changes incl. the already leaned mixture). What about range?
I would say that the fuel flow would stay the same as the engine driven fuel pump would still be spinning at the same rpm, however the mixture would now leaner so it would need to be changed (richer) to bring it back to the recommended setting requiring more fuel. I would imagine it would be a marginal increase and would be already be offset by the increased engine efficiency and more efficient prop AoA. Thus range would increase.
Correct. Wrong. Your thoughts?
