Failure detection is possible, but switching from IAS to TAS during flight will result in a step response in forces, the yoke would kick at the pilot.
A short detection delay would mean a short twitch where the yoke becomes weightless, ideally there would be none.
A low-pass filter to disallow sudden changes, would smooth over the change.
The final result of force change would be the red line in the attachment.
I added it to the experimental test release list.
