Why is my default B737-800 consuming so much fuel?

[durkheim]

I have just completed a flight from Sydney to Brisbane using the default Qantas B737-800. Upon arrival at the gate, I noticed that my left and right fuel tanks were completely empty and the centre tank had 32.4% of fuel left. I had filled up 50.9% of fuel in each tank before leaving the gate in Sydney and I am curious as to why the B737-800 had consumed so much fuel . Could it be due to the long taxi from the domestic terminal to 34R in YSSY or the steep rate of climb to 35000ft ?

P.S. I seem to encounter similar problems with other default B737-800s but not the B747-400.

It's due to the unrealistic fuel burns of the default 737 model.

Default fuel burn ain't great as torkermax stated. Long taxi shouldn't affect it greatly but steep climb...maybe. Standard AP vertical speed is usually 1800 feet a minute. Are you doing a steeper climb than that and what kind of throttle setting? And then if your tanks are full at takeoff there's all that extra weight climbing with you to fl350.

Apart from the fact that there isn't a default Qantas B737, what was the FSX fuel burn in pounds and what value did you expect?

There are repaints

There are repaints

Then it's no longer default. The .cfg file has changed.

Yeah, but the flight dinamycs are the same in all repaints, unless an addon air file is used.

I use FS9. I own Overland Simmer's Sky Boeing 737-800 with Brian Betts update. I can do a flight 2:30 at or above fl350 with 3500lbs of fuel

That is very well possible and that's great but, it is NOT the FSX default 737 as the OP had stated.

Forgive me for doing this, but...

What version of FS was that? I don't remember that one. What kind of plane was it?
