I had a post on here last summer when my approaches one day were messed up and my stall horn was just barely triggering - turned out I had a pitot-static leak causing my ASI to read higher than my actual speed. After I got it fixed, I did a lot of testing and note taking at various configurations to see, hear, and feel different speeds. The most significant learning was that my vents howl at 60 knots with 20 degrees of flaps. I learned to use my leaky air vents to double check my airspeed on final. I’d hate to lose my haunted howls, lol!
