STCA = Short Term Conflict Alert displayed on a controllers TAAATS/EUROCAT display. It highlights both aircraft, generates an aural and visual alarm that needs to be acknowledged (and as appropriate, the separation issue rectified) by the controller. There can be many false STCAs, there are few "real" STCAs, or at least should be very few if the system (including the controller and the pilots) operates correctly.
