Figure 6-2. Apply steering input to one side of the trailing edge to turn.  Attitude Flying Straight-and-Level Flight into the seat or raise the pilot against the seat belt.  Radial accelerations produce side loadings, which  will shift the pilot from side to side in the seat. These  forces need not be strong, only perceptible by the pilot  to be useful. An accomplished pilot who has excellent “feel” for  the PPC will be able to understand and coordinate the  rate of bank change so as not to overshoot the desired  course or bank, and ultimately be able to anticipate  the pendulum effect. The wing trailing edge control  surfaces move in the airstream and meet resistance  proportional to the speed and weight of the cart. When  the cart is heavy and flying faster, the steering con - trols are stiffer and harder to move because the wing  internal pressure is higher. When the cart is light and  flying slower, there is less force required and controls  move easier. The senses that contribute to “feel” of the airplane  are inherent in people. However, “feel” must be de - veloped. The flight instructor should direct the begin ning pilot to be attuned to these senses and teach an  awareness of their meaning as it relates to various  conditions of flight. To do this effectively, the flight  instructor must fully understand the difference be - tween perceiving something and merely noticing it. It  is a well established fact that the pilot who develops  a “feel” for the PPC early in flight training will have  little difficulty with advanced flight maneuvers. It is impossible to emphasize too strongly the neces - sity for forming correct habits in flying straight and  level. All other flight maneuvers are in essence a de - viation from this fundamental flight maneuver. Per fection in straight-and-level flight will not come of  itself. It is not uncommon to find a pilot whose basic  flying ability consistently falls just short of minimum  expected standards, and upon analyzing the reasons  for the shortcomings to discover that the cause is the  inability to properly fly straight and level. In attitude flying, the PPC pilot controls two compo - nents: pitch and bank. In a PPC, flying by attitude means visually establish - ing the aircraft’s attitude with reference to the natural  horizon. [Figure 6-3] Attitude is the angular difference  measured between an aircraft’s axis and the line of the  Earth’s horizon. Pitch attitude is the angle formed by  the longitudinal axis of the aircraft and the horizon.  Bank attitude is the angle formed by the lateral axis  with the horizon. 6-3 • Pitch control is the control of the PPC about the lateral axis by using the throttle to raise and  lower the nose in relation to the natural horizon. • Bank control is control of the PPC about the  longitudinal axis by use of the PPC steering  controls to attain a desired bank angle in  relation to the natural horizon.
