Measurements were made of the control motions and control forces during maneuvers regarded as likely to produce tail loads. The pitching motion of the airplane agreed well with that calculated, provided the equation of motion was not overly simplified. Structural deflections measured during the maneuvers proved to be small. It was found that pilots were inclined to allow the controls to return to neutral at a higher rate than obtained in the initial deflection, producing tail loads of which they had no physical awareness.
