The Trident in fact had an all flying tail, the column commanded the whole tailplane and what appears to be an elevator was in fact a geared tab, albeit quite a large one. So the pitch trim did not use an independent surface, unlike most subsequent CAT designs, and the distinction between a stick pusher and a MCAS-like device didn't arise. Hope that's clear
