🔄 ROLL CONTROL
The roll control exercise is designed to help the pilot become familiar with roll amplitudes and learn how to actively manage them. Similar to the Pitch exercise, this content consists of two main parts: simulating roll motions and dampening roll motions. 📐 Characteristics of Roll: Unlike the clean and symmetrical pitch motion, roll motion is never isolated and is always accompanied by pitch and yaw components. Still, the pilot should focus primarily on the "roll" part of this complex movement. Again, creating roll motions is always much more difficult than dampening them. 🎢 Roll Simulation Mechanism: It starts with a sharp brake pull combined with a weight shift to one side, let’s say to the right. At this point, the wing turns to the right, changing its course by about 45° from its original direction. At the same time, the wing tilts, misbalancing the CP-CG pendulum system. The heavy center of gravity (CG - the pilot) swings to the right to follow the wing (CP). Due to inertia, the CG will overpass the vertical position under the CP like a clock pendulum. If left alone, after 2-3 oscillations, the CG would naturally return to its balanced position under the CP. But for training purposes, the pilot needs to execute a switch-of-direction turn to properly roll the glider to the opposite side. 🎯 Switch-of-direction and Timing: The switch starts early, during the swing, somewhere between the lowest CG position and the highest point of the roll amplitude—where the body begins to lose speed and prepares to swing back. The moment of turning to the other side requires precise timing: 🛑 Too early: (Around the lowest position) The pilot cannot fully harvest the lower pendulum swing. 🛑 Too late: (Around the highest point) Speed is lost, the glider feels weightless, loses maneuverability, and cannot produce an energetic turn. The switch-of-direction begins with an energetic weight shift to the left. Even though shifting weight in the opposite direction to the left, the pilot continues to swing to the right by inertia. Then, just before the highest point (of the roll amplitude) causing a loss of speed, the pilot pulls the left brake sharply to turn the wing 90° left, amplifying the left roll.
