A333 heavier but same thrust as a A332 therefore A333 has a poorer power to weight ratio
The CF6 engines on the QF -300s are more powerful than the CF6s on their -200s. Not to say that the -200
doesn't still have a better power to weight ratio . . .
Incidentally, RR advertise the Trent772B as having the best "thrust to weight ratio" and "best takeoff and climb performance" for the A330. It's rated at 71100lb thrust. Go figure . .
Clear as mud? Back to the discussion. . .
