Jump to postAt lighter weight you actually burn less fuel, need to produce less lift, less drag. At MTOW the 744 is limited to about FL290 straight after takeoff, empty payload you can get a lot higher straight away which also saves fuel. Winds help the trip along as well, time of year also plays a part. They a...

Jump to postThe A300 rudder is relatively powerful because it is large, about 34% of the total fin chord. Rudder effectiveness also washes out with increasing sideslip, and this affects the critical anti-slip rudder more than pro-slip rudder.

Jump to postI think the real reason for burning of fuel would have been for a lower approach speed. A typical empty weight for a A320 would be 40t-45t, add 13.5t (133 pax) for pax and bags, from a max landing weight of 64.5t leaves 6-11t for fuel. Reducing the fuel load by burning it off will reduce the landing...
