A G1000 doesn’t have a backup CDI either so not worse than any factory new airplane.
Also the use of an absorbent pad you see in Hospitals amd medical offices is a good idea to place on the seat.
I was wondering what that was on the pilot seat of your C210, now I understand!
Why don’t people simply turn on the pitot heat every time? Especially if your only AI depends on it

Yes it does… A G1000 installation has two displays connected to different avionics units. Either of them can display the CDI.

There are many scenarios where you can lose both G1000 screens. Hence the backup AI + altimeter. The CDI does not have a backup.

It is a really nasty weakness in this product which loses a lot of functionality as soon as airdata (pitot etc) is lost.
The G1000 has similar integrity tests which would make it remove indicators, although not 100% the same as Aspen.
The pitot is a rather critical single point of failure and there are many reasons why you could lose your pitot. In IMC, this could ruin your day. Larger airplanes (e.g. TBM) have 2 independent pitot static systems.

I really don’t see any scenarios where you lose both G1000 screens without also losing the whole electrical system. In that case a separate CDI won’t help.
Do you have an example?
I think the answers are in the thread I linked to, or a similar one. The G1000 can lose it too but it uses GPS data for the background gyro erection / integrity checks, whereas the EFD1000 uses airdata which is arguably a lot more vulnerable.
Is the NAV/COM display not usable at least for localiser backup?
I think they had an Aspen not a 1000 in the 210.
Here’s their flight from Nuuk to Kulusuk, and then on to Rejkjavik:
In “live” terms, they still seem to be somewhere in the east of Austria.
