Larry and Otis,
You would both be correct IF your assumptions of what is happening inside of the little black box (GSU 25) were correct.
There are 3 axis gyros and accelerometers inside the GSU 25 which are used in complex algorithms written by some of the smartest engineers (not me
) to output an attitude solution as well as the turn rate indicator and slip skid indicator.
Because acceleration data is used by the system, an erroneous acceleration due to GSU placement would have a negative affect on performance of these indications. As stated in an earlier post, the G3X Install manual covers what locations are acceptable. If you follow this guidance, you will not have an issue.
Another simple way to think about this is to take the example of the slip skid indicator, which is a measure of lateral acceleration. If the GSU was in a wingtip and you did an aileron roll, you would measure lateral acceleration, but you could still be perfectly coordinated.
Thanks,
