I can’t say I notice the density altitude when I’m either cruising or thermaling. I did notice it when I was towed up. John Scott and I were noticeable lower going over the west end of the runway. Even with the west wind at about 10 knots the lift off took longer and we crossed the west end of the field around 150 to 200 feet. On a more normal day the west end crossing is more like 200 to 300 feet agl. John Lincoln
