Why do planes need rudders?
Unlike a boat, the rudder is not used to steer the aircraft; rather, it is used to overcome adverse yaw induced by turning or, in the case of a multi-engine aircraft, by engine failure and also allows the aircraft to be intentionally slipped when required.
Is the rudder used in flight?
The rudder is used to control the position of the nose of the aircraft. Interestingly, it is NOT used to turn the aircraft in flight. Aircraft turns are caused by banking the aircraft to one side using either ailerons or spoilers.
Can planes fly without tail fin?
If the plane loses just a small part of of the fin, it might be ok, but if it loses the fin completely two major things happen: The plane becomes unstable in yaw. If the plane needed such a big surface behind its center of gravity (CG) to be stable there is almost no chance of flying without it.
Can a plane be constructed without vertical stabilizer and rudder?
Without the vertical stabilizer, the aircraft would loose the stability in the yaw axis. So not only is the ability to control the yaw axis lost (because of the missing rudder), but so is the device that makes the aircraft stable in the yaw axis. Conventional airliners cannot fly without the vertical stabilizer.
