B767-300ER Fuel Flow

[Asianboy]

Can anyone please remind me of the total crz fuel flow of a B767-300ER at MTOW at ISA?

Fuel flow would be dependent on;
Altitude, Speed, Engine type (as well as temp and weight which you mentioned) and probably some other stuff that those in the know would, erm, know. :confused:

By the way... If you're cruising along at MTOW, then surely you would have had to have departed at a weight greater than MTOW?? Do you mean after departing at MTOW, or actually cruising along at that weight?

If you find the performance charts, it shouldn't be too difficult to work out.

I'd guess somewhere in the mid 2000's KG/hour for each engine.

Thanks Sapperkenno

I don't have the performance charts to hand, hence the query.

I was only looking for a ball-park figure: not for an operational one, so

your guess is in line with mine, ca. 2500/eng/hr. at say, 130000kg crz weight, LRC; F330; ISA conditions; no anti-ice.

Thanks for your input.

A 767 departing at MTOW will burn a little in excess of 5000 kgs pr. hr. initially. Positioning an empty aircraft with little fuel, will see around 4000 kgs.

If you want to talk heavy weights - at 180 000kg, FL330 and ISA, you are burning about 6000kg/hr. At 130 000kg it would be about 4500kg/hr. Empty (say 100 000kg), about 3800kg/hr.

Those figures will of course vary with engine type and cost index.
