Good one!

I notice that student is training in an aircraft with a constant speed prop. Ain't no LSA!

Nice catch, Paul!

That's a Cirrus cockpit, I think.

No prop control on a Cirrus.

Really, an SR22 is fixed pitch? Or does it have some throttle/prop interconnect?

The latter. A single "Power Lever". Full throttle gives max prop rpm. Initial rearward travel drops rpm but keeps (essentially) full throttle. Keep pulling back and eventually MP and rpm fall together. Quite an elegant solution, though some pilots have expressed a wish that there was a blue knob - and one company came out with an STC to add one.

Doesn't that take away a lot of pilot options for power and prop settings?

It does but I think most Cirrus drivers prefer not having to mess with a prop lever; they prefer to play with the mixture to achieve their own flavor of LOP. That's just based on reading the COPA forum. Cirrus was all set to offer a FADEC engine a few years back but the pilot community then really balked at not being able to do their own fuel alchemy ...

My personal view is the computer will likely do a better job than me so one lever works fine from my perspective ... But that's just one man's opinion...

Cheers

If you think about it, the Rotax community has adjusted well to what I call "poor pilot's FADEC": fixed pitch prop and self-compensating carbs. I for one don't really miss the extra two levers.
