How much does it burn ?

[long-courrier]

I'd like to know how much fuel some aircraft burn per hour ?
let say MTOW , no wind.
average figure is perfect for me, i just wish to compare 777 747 340 320 ( or any type )
tks

[hetfield]

A300

about 5.000kg/h


A340/200

about 6.000 kg/h



B727

about 3.600 kg/h

[Mac74]

B744

about 12.000 kg/hr

What's wind got to do with it?

[NoNameRecord]

B767-300 ER (PW4060)
Fuel usage during taxi: 26.5L (7 usg) per minute
Fuel usage during take-off: 6L (1.6 usg) per sec
Average fuel usage during flight: 6250L (1651 usg) p/hour

MTOW= 186.880Kg (407,000 lbs)

long-courrier,
You should really have specified when.
There is a huge difference between take-off and early climb-out, and cruise.
Anyway you got some figures.
Hope they answer your question.

[SpootNICK]

DC-10-30 BURNS 9500 KGS / HR When Heavy, drops to about 7500 KGS / HR when empty. MTOW 256T

[mcdhu]

A319 - 2000 kgs/hr
A320 - 2400 kgs/hr
A321 - 3000 kgs/hr

[411A]

L1011, standard body or short body (-500), average 8,000kg/hr, all economy seating (-500, 309 seats, standard body aeroplane, 362 seats...400 possible with large rear doors).

[AtoBsafely]

B744: I'd say average is more like 11,000kg/hr. 12T at level off when heavy, 10T or less late in the flight.

"any type"?

Cessna 152 or other 2-seater (Skipper, Traumahawk) with 100-115hp engine - about 16Kg(6 gals.) ph

4-seat/4cyl basic flyabout (Piper Warrior/C172) - 150hp - about 22Kg(8 gals). ph

6-cylinder Saratoga or similar - about 30Kg(11 gals.) ph

In small planes we tend to measure fuel in gallons, but I add Kg conversions for consistency.

The medium-heavy iron burn up the equivalent of 3 small planes per hour (not 3 times the fuel - three complete airplanes fully loaded!)

[Phil Squares]

For the 744, 17 T first hour, if heavy the 12 T for 5 hours then 10 T for the remainder of the flight.

10t/hour works for medium weights.

Fuel Burn

Long-courier, as a rough rule of thumb B747 classic with full load of pax on long haul flights you can use 12000 kgs / hour average. e.g. HKG-SYD flight time average 8.5 hours, average fuel burn 102000 Kgs.

[Tofu Racing]

As a matter of fact, it has nothing with aircraft type - it depends on engine and engine thrust settings. Multiply SFC - Specific fuel consumption (fuel kg/or lbs per hr per kg/ or lb of thrust) with thrust settings and you'll get what the engine is burning for a given thrust settings.

[roljoe]

exact Tofu...nevertheless as the question sounds quite basic..

for a Learjet45, about 1400 lbs/hour in cruise condition..;and the wind has nothing to do..it should be considered like a parameter wich increases or decreases the lenght of the flight...and therefore reduces or increase the Total fuel burned for the trip..

Errr...Hang on Mate...isn't it the wind that goes down them intakes...?

[SNS3Guppy]

Errr...Hang on Mate...isn't it the wind that goes down them intakes...?

Aaah...no. It's not.

Hi, so considering your statement...

a no wind day condition..will ground all jet a/c !!!!

[rada76]

For comparison have a turboprop!

SAAB 2000: 1st hour about 1000kg, subsequent hours 900kg.

Therefore 1 hour flight = 1000kg

2* 1 hour flights = 2000kg

But 1* 2hr flight = 1900kg

Burn holding for departure = 400kg/hr

Hope this helps?

Climb profile= 240kts then Mach 0.50
Cruise= Mach 0.62
Descent Profile Mach 0.62 then IAS 275 Then IAS 250 Below FL100

Engines are AE2100E's
