This helps achieve enough airspeed to complete the roll without losing rudder and aileron control. These slips are performed by applying opposite inputs of the aileron and rudder controls. Yawing generates side forces due to incidence at the rudder, fin and fuselage. Steering was controlled by a single balanced rudder. Steering was controlled with a single rudder.
