why does an A380 have 4 engines but carrys nearly twice as much as a 747 which also has 4 engines? why does an A340 have 4 engines but a777 has 2 engines but has a longer range and the difference in payload is not very much? the 707,727 and the 737 have more or less the same range and payload but they have 4,3 and 2 engines respectively. why does the 787 have 2 engines and is faster and uses less fuel? who knows about the A350 or the 747-8?
