If I recall correctly, you can change the instruments to show actual airspeed.
Been a while though, so I could be wrong.
I used to have a 1967 C-172. I considered myself lucky to make 110mph indicated. My indicator was marked in Mph. I think 110mph is about 95kts. N3760R was a good little plane. We sold it. Then that guy sold it and the guy that bought it didn't handle a crosswind gust and wrapped it into a ball on the way home with it. He lived, but I'm sure he was pretty upset.
