GFF A330-200

[Natstrackalpha]

Can anyone say what the gross fuel flow is of the A330-200 using the RR Trent 772B


at say FL410 - OAT -56.5


and FL330 - OAT -51


please in KG per hour both engines.


Assuming a temp dev of 0.


Assuming TOW 233T


Thank you.


Also - if you are feeling generous can you also give me the fuel consumed from a straight climb to FL330 - please.


-and also the descent from 330 to say 2,000` - which I am guessing to be around 1000 kg both engines or 500kg each engine - based on nothing in particular.


again - thank you.

Have you considered consulting a copy of the FOM?:E

Ok

Brakes release of 232.3T
to FL330

Time : 24 mins

Distance : 147nm

Fuel : 5118 kg

Average TAS : 368kts

Which means you will be TOC FL330 at around 227T. Im lazy now so these figures are just from the book no interpolation.

FL330
230 T M0.8 3263kg/hr/eng IAS 284 TAS 465

220 T M0.8 3146kg/hr/eng IAS 284 TAS 465

Optimum weight for final step climb FL370 to FL410 is about 176T
take about 4 mins and 350kg rough interpolation eyeball.


FL410 170T M0.8 2391kg/hr/eng IAS 237 TAS 459

FL410 180T M0.8 2570kg/hr/eng IAS 237 TAS 459


Descent from FL330 or FL410 TO 2000' ?

From FL410

150T 403kg 21mins 129nm
200T 460KG 24mins 148nm

Hope this helps
