Mad Jock, apologises
I thought I read further back someone wanted the Vmcl. I just gone back and it was Vmca as you have pointed out. 1.1 Vmca based on ISA conditions and SL is 108kts so approx 98kts.
Stall speed is obviously variable given config and weight but a rough guide for 23T clean airframe is about 117 CAS (ATR don't offer any other charts)
