Banking is performed with the following steps  [Figure 6-9]: Flight controls are used in close coordination when making  level turns. Their functions are:  When an aircraft is flying straight and level, the total  lift is acting perpendicular to the wings and to the Earth.  [Figure 6-10]  As the WSC is banked into a turn, the lift  then becomes the resultant of two components. One, the  vertical lift component, continues to act perpendicular to  the Earth and opposes gravity. Second, the horizontal lift  component (centripetal) acts parallel to the Earth’s surface  Changing the direction of the wing’s lift toward one side or  the other causes the aircraft to be pulled in that direction.  Turns are classified to determine the bank angle as  follows: A. Straight  fl ight B. Pilot applies sideways pressure to the control bar  shifting the weight towards the direction of the desired  turn initiating the bank. C. Turn is established and maintained by moving the  control bar back to the center position.  D. Pilot is maintaining stabilized bank and a resultant  turn. E.  Pilot shifts weight to opposite side to initiate exit out  of the turn. F. Straight  flight is established and maintained by moving  the control bar back to the center position.  •  The WSC is banked with side to side pressure with the  control bar and the bank angle established determines  the rate of turn at any given airspeed.  •  The throttle provides additional thrust used to maintain  the WSC in level fl ight.  •  Pitch control moves the nose of the WSC aircraft up  or down in relation to the pilot and perpendicular to  the wings. Doing this sets the proper pitch attitude and  speed in the turn.  •   Shallow turns are those in which the bank is less than  approximately 20°. •   Medium turns are those resulting from a degree of  bank that is approximately 20° to 45°.  •   Steep turns are those resulting from a degree of bank  that is 45° or more.
