GFF A330-200
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.

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
