motorgliders as towplanes

For purposes of analysis, the angle at which the tow rope meets the glider is the angle to consider that THRUST is acting on the glider. *A rope can only be in tension. *It cannot impart any rotational "moments" to the glider. Unless the hook is on the centreline and the tow rope is pulling stright ahead, it certainly can apply a moment. Simplest case: low down belly hook, pull straight ahead, pitch up. Ian
