The other day I was flying home from the Penticton, BC. I was half asleep on the departure. Even though I was half asleep I remember thinking, "dude left rudder." I opened my eyes and sure enough we were rolling into a left turn. We must have been in a slight slip on turn entry. This is the first time that I can think of that I was able to tell which rudder direction was needed without the ball. It got me thinking. Would the assometer be able to tell the difference between a slip in one direction compared to a skid in the other? Assuming ones eyes were closed.
