The current installations of the G1000 and Avidyne systemes only have a
single AHRS. You could still likely use them for charter though a
redundant
AHRS, as planned for the Mustang, would be a good idea.

Any equippage for jets less than at least a single Flight Management
System
(FMS) is rudimentary and probably lacks RSVM and other important
capabilities.
A G-1000 is great in a Cessna 182, but not so red hot in a jet that goes
to
flight levels.


I don't think you are comparing apples to apples. The Mustang G1000 system
will not be as limited as the 182's.

I have a lot to say about Cessna that is negative, but I haven't yet seen
anything that would lead me to believe that they are going to produce an
unsafe jet.
