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's my understanding that the conflict resolution algorithm is based on
much more realistic assumptions, so that climbing and turning flight of
the potential threats is included. The simple assumption of straight
flight might have been used in the very beginning, but no longer. If you
have a recent reference that suggests otherwise, I'd like to know about it.
