The control system leaves its mark on the style of control of the A321: despite the weight comparable to the Boeing - 757-100, the liner is distinguished by a faster reaction to sidestick movements during cruise flight, which requires special care from its pilots.
It also has a fly-by-wire control system, but accommodates more passengers (185 in a two-class configuration), flies further and higher. The Airbus A321 is a further development of the A320 and a direct competitor to the legendary Boeing - 757.
