The tow pilot strives to maintain a steady  pitch attitude and a constant power setting for the desired  climb airspeed. The glider pilot uses visual references on the  towplane to maintain a proper lateral and vertical position. In a level flight tow, the pilot should position the glider  above the wake of the towplane. Low tow offers the glider  pilot a better view of the towplane and provides for a more  aerodynamically efficient tow, especially during climb, as  the towplane requires less upward elevator deflection due to  the downward pull of the glider. However, because of the  risk of towline fouling if the towline breaks or is released by  the towplane, low tow should be mainly used for level flight  aero-tows such as for a cross-country flight. Climbing turns are made with shallow bank angles in the  high tow position. During turns, the glider pilot observes  and matches the bank angle of the towplane. In order to  stay in the same flightpath of the towplane, the glider pilot  must aim the nose of the glider at the outside wingtip of the  towplane. This allows the glider’s flightpath to coincide with  the flightpath of the towplane.  [Figure 7-7] If the glider’s bank is steeper than the towplanes bank, the  glider’s turn radius is smaller than the towplane turn radius.  [Figure 7-8]  If this occurs, the reduced tension on the towline  causes it to bow and slack, allowing the glider’s airspeed  to slow. As a result, the glider begins to sink relative to  the towplane. The correct course of action is to reduce the  7-7 Figure 7-7.  Aerotow climbing turns. During a turn, the glider flies the same path through the air that the towplane flew.
