The difference between the speedometer readings before 2.13 and after are very noticeable. On take-off before 2.13, my landing gear would start to creak at about 145-150 mph; after 2.13 the creaking starts at about 100 mph. Climb-out speed before 2.13 was about 160mph; after 2.13 it reads out at 90-100 mph. In the AH Training Squad classes conducted by Rolex last summer, he said, as I recall, that the minimum speed needed to execute a vertical maneuver such as an Immelman is typically around 240 mph. That was true of my vertical maneuvers in a Niki before 2.13. Post-2.13, the minimum speed is around 170-180. It seems reasonable to conclude from the striking difference between the pre- and post-2.13 speedometer readings that they can't both be correct. I don't claim any expertise in these matters, but if I was forced to guess whether the pre- or the post- is correct, I'd have to go with the pre-. If we are stuck with the speedometer settings as they currently are, then I guess we'll just have to get used to it.
