Below is a comment sent to me by James (jsrickel) this morning:

It might be a good idea if we all leave feedback on the A2A forum mentioning the gauge read error. I haven’t yet experienced it myself since my flight simulator computer is not complete, but I trust what you are experiencing and, no doubt, will experience the same when I get it up and running, unless A2A fixes the problem. We can back you up by helping to make them aware of the problem.

It’s a good idea since so far I see no one but me raising the FIP reading issues in the forum.   If so, the chance for getting a fix in the coming update patch is minimal.

If you have FIPs and the aircraft, or if you are planning to get it, let’s leave a comment about the problem at A2A’s C172 Training Support Forum here to raise the company’s attention.
