2.  The response of the controls to the pilot’s touch is  another element of “feel,” and is one that provides  direct information concerning airspeed.  3.  Another type of “feel” comes to the pilot through the  airframe. It consists mainly of vibration. An example  is the aerodynamic buffeting and shaking that precedes  a stall. Different airspeeds and power settings can also  provide a subtle feel in aircraft vibrations.  1.  Bank control—control of the aircraft about the  longitudinal axis to attain a desired bank angle in  relation to the natural horizon. This can be easily seen  in a WSC aircraft by looking at the angle the front tube  makes with the horizon.  [Figure 6-5] 2.   Pitch control—control of the aircraft about the lateral  axis to raise and lower the nose in relation to the  natural horizon.  3.   Power control—used when the flight situation indicates  a need for a change in thrust, which at a constant  speed raises and lowers the nose in relationship to the  horizon similar to pitch control.   Kinesthesia, or the sensing of changes in direction or speed  of motion, is one of the most important senses a pilot can  develop. When properly developed, kinesthesia can warn the  pilot of changes in speed and/or the beginning of a settling  or mushing of the aircraft. The senses that contribute to “feel” of the aircraft are inherent  in every person. However, “feel” must be developed. It is a  well established fact that the pilot who develops a “feel” for  the aircraft early in flight training has little diffi culty with  advanced fl ight maneuvers.  Flying by attitude means visually establishing the aircraft’s  attitude with reference to the natural horizon. Attitude  is the angular difference measured between an aircraft’s  axis and the Earth’s horizon. As discussed in Chapter 2,  Aerodynamics, pitch attitude is the angle formed by the  longitudinal axis, and bank attitude is the angle formed by the  lateral axis. Rotation about the aircraft’s vertical axis (yaw)  is termed an attitude relative to the aircraft’s fl ightpath, but  not relative to the natural horizon.  In attitude flying, aircraft control is composed of three  components:  Flying straight and level is the most important flight  maneuver to master. It is impossible to emphasize too   Straight-and-Level Flying  Attitude Flying  Figure 6-5. Pilot’s view of 45° bank angle can be measured with the front tube or the control bar’s angle with the horizon. 6-4
