G'Day,
-200 series is the long range version. Having said that QF has it configured for domestic only ops (no t/c rest only 1.5 galleys ect).
-300 will be coming with business class sleeper seats and will do aust-hkg, aust-japan from jul-aug 03.
The -300 does not have a CWT
The aircrafts fuel management system pumps gas in cruise to the stab tank ino order to minimise drag. FBW takes care of the C of G calculations
