Gone West
done it, not by choice, didn't have any noticeable effects on the G1000
the GMU should be able to correct any AHRS fubaring that goes on

I've done it once or twice, a long time ago. I don't remember anything terrible happening.
The G1000 doesn't have any moving parts, so I can't think of any components that spinning would be hard on.
Also, for what it's worth, I believe the new T-38 military trainers have glass cockpits and obviously those go through more rigorous aerobatics than a simple spin. I think glass cockpits are reasonably aerobatic-friendly in general.
You should be fine.

I don't think it would add any significant wear to the standby AI. If you were spinning the plane on every flight for months in a row, that might cause problems, but not a couple of training flights for a CFI applicant.
Now for some thread creep...does anyone know why specifically tumbling is hard on gyro instruments? Everyone says it is, but I've never been told exactly what wears out and why. I'm starting to wonder if this idea is similar to shock cooling.

You don't want to spin a -38!T-6 you mean?
I said "rigorous aerobatics" but that doesn't necessarily mean spins
Of course now that you mention it, I think the Texan IIs have glass cockpits as well, don't they?

No, that's the truth, I've done the same thing.
I believe it happens because the system is continually cross checking itself. It crosschecks heading versus ground track, airspeed versus groundspeed, altimeter versus GPS altitude, etc. to help determine if any individual components have failed. This is actually a safety feature. The moment it detects a problem with a component it removes it from the display and places a red X through that area of the screen. This is so a pilot won't get erroneous information that can become distracting in the same way gyros slowly spin down after a vacuum failure.
When it happened to me, I didn't have to reboot it though. It fixed itself as soon as I started moving forward again.
That is about the only thing a spin is rough on and even then that isn't nearly as bad as high g-load turns. A spin doesn't put much force on an aircraft at all, many newer gyros won't even tumble when spun. But take that plane and put it in a 4G turn a few laps around and watch them tumble like nobodies business.
As for the g1000, like was previously said, no moving parts so don't worry yourself.
What are you pulling 4Gs in?
