It pitches for IAS (within limits set). No auto-throttle.
I think I see your confusion though as Bob's comment seems to imply a coupled approach and IAS. The pilot is definitely required to manage throttle.

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.
