Hi Robert,
The full scale pilot was reading his altimeter which was reading MSL (Mean Sea Level) So whatever the altitude he was reading minus your field elevation was the altitude of the sailplane. Last year at the SW Classic I did a couple of fly-overs in my RV7. The lowest was about 500' the highest was about 1500. At 1500' the planes sitting on the ground were tough to see. Interestingly, many years ago at our old field in Gilbert AZ we did some experimenting to see just how far down range we get. I was flying my Psyko and got as far away as I could and still maintain orientation. A crew on the ground drove to the area and measured just under a mile away. I was very surprised but it was a real test with real numbers. Darwin N. Barrie Chandler AZ |
