Fw-190 Throttle Detent

[Kira]

Anyone ever notice this?  What's it for?

 

I was messing around with trim and sliders and got messing with the throttle when I noticed that in the FW-190A4's cockpit, (actually, all 190s have it) the throttle has a detent (okay, really an offset) between 0-22% throttle and 23-100%.  Any idea what this was for?  My guess would be that lower range would be warmup settings?

Looks like it's designed to keep you from reducing throttle below 25. It's smooth on the way up, the stop is on the way down.

 

Air cooled engine, possibly to keep you from shock cooling it.

Ahhh, shock cooling (and avoidance thereof).  Of course.  That makes sense.
