MEAD AND HUNT INC. Consulting Engineers Post Office Box 5247 2320 University Avenue Madison, Wisconsin 53705-5247 608-233-9706 September 10, 1986 Mr. Richard Ashley 1005 Tipperary Road Oregon, Wisconsin 53575 Subj: Private Airport Dear Mr. Ashley: Based on our visual inspection of the turf landing strip which you showed me on the Weiman property located on Lot 2 of the Certified Survey containing your property as Lot 1, I have the following comments: 1. Design criteria for a public use runway per the Federal Aviation Admini- stration (FAA) Advisory Circular (AC) 150/5300-4B, changes 1 through 8, shows a minimum 2,700 foot paved runway for a Basic Utility Stage I air- port. 2. Chapter 4, Paragraph 14, c. of AC 150/5300-4B states that runway lengths may be obtained from the airplane flight manuals. These lengths vary based on a number of factors including: a. Temperature, pressure and humidity. b. Wind direction and speed. c. Runway gradient and weight of aircraft. d. Runway surface (turf, dirt or paved) . 3. From the Cessna Model 172P manual dated May 26, 1982 (which may or may not be the model of Cessna that Mr. Weiman owns) the following lengths are needed. a. Takeoff distance (2200 to 2000 lbs. ), dry turf strip (add 15%' to ground roll ), 68°F, 9 knot headwind (decrease distance 10%) . 1 . Ground roll required is 862 feet. 4 2. To clear a 50 foot object is 1485 feet. 4 b. Takoff distance (Max. weight 2400 lbs. ) dry turf strip (+15%), 68°F, 9 knot headwind (-10%). 1. Ground roll required is 1061 feet. 2. To clear a 50 foot object is 1829 feet. c. Landing distance same conditions (increase ground roll by 45% in- stead of 15%). 1. Ground roll required is 751 feet. 2. To clear a 50 foot object is 1437 feet. I Founded in 1900
