Fuel Burn for A320

Mon Feb 10, 2020 5:54 am

Does anyone know how much fuel an A320 burns per hour?

CFM56 powered A320 has fuel.consumption around 2400-2600kg per hour.

IDK about Kilos but a very common US operated A320 CEO will do about 2450 a side. NEO about 2100-2200 a side. All per hour at a reasonable cruise altitude.

Airbus had this table in one of their documents, these are not guaranteed levels

That works out to be 2537-2625 kg/hr for the A320, and 2005-2063 kg/hr for the A320neo

Which engines for the CEO?

These figures look pretty high to me. When I flew new(ish) IAE powered CEO’s they burned ca. 2200-2300 kg/h.

We often assumed a figure of 2400kg/h for gross calculations, but the actual burn was rarely that high...

They are not cruise burn figures, rather total fuel burn, this is for the A320ceo

strange the % delta is rather small:
14722 / 15273. = 0.963 ~~ 4.7%
7265 / 7611. = 0.95 ~~ 5.0%
3844 / 4074. = 0.943 ~~ 5.7%

You seem to have forgotten to take the difference in sector length into account.

In the first case

14722/15273= 0.963 x (349minutes/428minutes)= 0.786 ==> total difference 21.4%

That's fantastic! Its great to have insight like this. Is this a public document? any chance there is this same breakdown for the NEO? Or weights?

Sorry for all the questions but spreadsheets and calculations are already forming in my head...(I'm such a geek).

Yup auto facepalm. :-))
( why would anyone do a comparative list CEO / NEO tagged Mission 1, Mission 2, ... and then use different Missions length? )

That would be an apples to apples comparison. We never do that on a.net.

The document is called “Getting to Grips with fuel economy and emissions reduction”, it’s a bit dated now, about 5 years old. Now sure where on the web it would be available.

No does not have the same details for the neo, nor weights. But I guess they would use their standard marketing passenger + baggage loads.

It depends on the weight and what part of the segment you are on... first hour? Third hour? Sharklets? New frame or old frame?

Generally, later cruise mid thirty’s IAE per side fuel burn a320 sharklet is about 2500/Hr per engine.

I was flying an a321 neo PW this week, the fuel fluctuates more then the IAE, but that was probably around 2600-2700lbs.

These are the numbers that I would expect, A320 burning 2250 kg per hour (A320 with winglets LRC at optimum altitude) with a gross weight of 64,7 t (1/28,5 of gross weight per hour)
A321neo burnig 2400 kg per hour would be for 79,500 t gross weight (LRC, optimum altitude, 1/33 of the gross weight). 79,500 kg is a DOW (50 t) + 20 t payload + 9,5 ton fuel -- still 3 hours before landing.

My model implies that the NEO burns some 17%-18% less for the same gross weight at an optimum altitude.
