What is forward slip in aviation?
It is a technique you use to lose altitude quickly without gaining airspeed.  It is not efficient aerodynamically as it causes significant drag.  The plane will appear as if it is flying sideways.  A forward slip is executed by applying aileron input with opposite rudder.  Typically full opposite rudder is needed to compensate for the aileron input.
