You shouldn't see split-elevators on a 727 with hydraulics on. A MD80 is a
different story though. This airplane does not have powered elevators but
uses old-fashioned control tabs. What this means is that without airspeed
the elevators, and ailerons for that matter, can flop around and go where
ever they want. The MD90 does have fully-powered elevators but the
ailerons are still control tabbed.
