Why does airspeed change when I adjust the prop?

Kev,
The company line is that, while they tried to design to avoid spins,
the chute is the answer for loss of control:

That's not only the company line. The chute is the basis for spin certification both for the FAA and (as
you pointed out) the EASA, accepted as an alternate method. It seems to work pretty well, too.

I did run across one quote from the Cirrus president, who said he
"wished they'd demonstrated a normal spin recovery to the FAA".
That's interesting, because it sounds like it's at least possible.

Cheers,
