QAVION, ATFQ!
The cruize f/f on the 340 ranges from 8t/hr at the for a heavy wt/lowish level cruize, to 6t/hr for opt alt/light wt. As for the -400, I think its around 9-12 t/hr. Measured in kg/hr in CX. There is a kg/anm (or something like that) on the flight plan, but with all the electronic wizardy available for opt alts etc, it is not refered to that often.
340 = N1/2 spool
-400 = EPR/3 spool as with most rollers
Read the `Green Book`, apparently it has most of the up to date info. Or tell me your e-mail, and I`ll fill in any gaps for you.
As an aside, on the 330`s which basically have big RB211`S (400 donks) most guys set thrust ref N1 anyway, EPR is non~sensical.
I know 95% N1 means a lot of noise, but what the hell is 1.15 EPR?
