The other thing to consider, beside the sensible advice
below is:- Is the glider able to carry any more weight,over and above that of the pilot. Many earlier generation glass gliders Cirrus,Asw15.Libelle,Astir, the max cockpit weight is limited by the max all up weight, resulting in cockpit max weights of much less than 110kg, The addition of lead in the tail to adjust the C/G would only result in reducing cockpit load even more At 09:00 03 January 2004, Chris Rollings wrote: It's an accepted and widespread practice to put lead in the tail to get the C of G where you want it. However, be aware that although a glider with a heavy pilot and tail ballast may well have the C of G in the same place as one with a light pilot and no ballast, its spinning behaviour may well be quite different due to the greater rotational inertia. In general a glider with a heavy pilot and tail ballast will have a greater tendancy for the spin to flatten, and recovery may be more difficult or at least slower. Gliders with tail ballast, particularly if carried fairly high up in the fin, are also more likely to suffer damage in ground loops.

Each glider has or at least should have provisions to install this type of weight to make sure the glider flies within the required C of G. Udo Is it acceptable practice to put lead in a gliders tail to counter the weight of a large pilot? David R. |
