Elevator?

Elevator („Hoehenruder“)? Do we have such in a Tiger?

And what does this mean:
Bei dem betroffenen "Tiger", so der neue Bericht, sei der "normalerweise verfügbare Steuerweg in der Nickachse" allerdings erheblich eingeschränkt gewesen. Folglich steuerte der Autopilot mit dem "Steuerausschlag ganz vorne" in einen "unkontrollierten steilen Sturzflug".
What is „normalerweise verfügbarer Steuerweg“? Normally available control travel?

Loosely translated: Available control travel around the pitch axis was restricted. Hence, autopilot gave full nose down input.

Has this to do with ‘envelope protection’? Like as if under normal conditions full FRW or full AFT control input of cyclic (or whatever elevator a Tiger has) only translated to minor nose down, or nose up response? And maybe at the mishap moment an alternate control law being in effect, which mapped full cyclic control input to equally full ‘elevator deflection’? And finally, the autopilot not being aware of the alternate law in force?

How does this all work?
