I came across this question when I am playing my FS 2000 B747-400 proffesional pack.
At what Vspeed and IAS generally does a B747-400 climb when it took off from maximum take-off weight in reality? On my FS2K, I am about half of the maximum take-off weight of the B744, climbing to FL350, only passing 15,000 feet and with a IAS of 270 knots, I am at full power. If this is the case, how does the B747-400 climb in reality with full weight? And, I virtually cannot climb when I took off on Maximum take-off weight but in reality I see those close to MTOW B744s can climb at a reasonable rate. Or is it just FS2K inaccuracy?
Can someone explain to me what are the procedures to climb a B744, may it be light or heavy? I would really love to know.
Thanks a lot
