The glider does not need to have TCAS installed, only a transponder, in
order for the other aircafts TCAS system alert for an avoidance
manuever.


Ok, but the advice emitted by the TCAS in the other aircraft is based on
the
assumption that the glider will keep its flying level and this is not
true.

It is far better than no warning at all. The pilots of the TCAS equipped
aircraft will at least get their heads out of the cockpit and take a look
out of the windows.
