Nothing better to do yesterday so I took the bugsmasher for a little ride to check my stall speed. Using a GPS and flying the 4 Cardinal points my average stall speed worked out to 49.5 knots. My indicated airspeed was 10 mph faster.
Playing around I checked my ASI at 80 mph and got an average speed of 60 knots.
Finally I checked my cruise speed at 2400 rpm and I was about 10-11 mph faster on the ASI than GPS.
A couple of weeks ago I did a few hours of circuits trying different approaches and speeds and set it up just by feel/gut and glanced a few times at the ASI and it was just under 90mph on a consistent basis on a normal approach and around 80mph on short field landing approach.
After my check of the accuracy on the ASI I can see that my real airspeed was about 10 mph lower or 80mph normal and a little over 70 short field.
Sorry to mix up knots and mph but my GPS was reading knots and my ASI is mph.
