No autothrottle. He was I think referring to non-precision, step down type approaches. I use the GRT Hx to drive the Trio, and it gives me the option of making step down descents holding either IAS or VS constant at a selected rate. (VS recommended). When there’s a glide slope, those settings are ignored.
