Page 11 SUPPLEME :‘7’3 : MATEhrHL IN BACK OF BOOK Page 1 126705 In the area of Lansing and East Lansing, there is but one airport. With the steady increase in flying, both com- mercial and private, it is apparent that with future expan- sion, a greater number of airports must be constructed: £13.23. The proposed airport is located one and one-half miles south of muchigan Avenue on Harrison Road. It is a quarter section lying southeast of the intersection of Harrison Road and Mount Hose Road. The property is owned by Michigan State College. The airport would be centerally located be— tween Lanshig and East Lansing, being about a ten-minute drive from Lansing, and about a five-minute drive from East Lansing. The roads leading to the airport are of bituminous pavement. The airport has an elevation of about 860 feet, and the surrounding country is suitable for emergency land- ings. It is so located that planes landing or taking off will not fly over either Lansing or East Lansing, thus eliminating the hazard of flying low over pepulated dis- trios. The airport is located on the Pennsylvania Central Airlines between Lansing and Detroit, and the prevailing winds are such that the smoke from the cities will not drift_in that direction. Rating: The airport comes under the landing area classification of 1. Airports are classified by the length of the effective Page 2 runways or landing strips, based on freedom of obstruction in the direction of takeoffs and landings. At the present time a gliding ratio of 20 to l is sufficient. Requirements: The requirements for a class 1 airport as set up by the Civil Aeronautics Authority are as follows: "Class 1, land- ing area shall be sufficient to permit the safe Operation of private planes of the size now in use. For purposes of airport planing, a landing area located at sea level, whether its landing area be of the *allway or landing strip type, will be considered for inclusion under the ’1' class— ification if the landing area provides a sufficient number of landing strips at least 300 feet wide, and having a min- imum effective length of 1500 feet, or permits the poss-. ibility of laying out such strips if an allway landing area, making possible, landings and take—offs to be made within 22§° of the prevailing wind direction for at least 73% of the total winds of over 5 miles per hour velocity. For landing areas located at higher altitudes, the same general requirements as to landing fields apply with the exception that the minimum effective length of 1500 feet must be increased by the percentage shown in Figuni 1. All landing areas should be adequately fenced.” Earthwork: The airport is graded so that the entire field is available for use. The earthwork was computed using the Page 3 barrow pit method. Cute and fills were only partially balanced, because to balance them would lower the entire elevation of the field. About 161,000.00 cubic yards of earth is needed to complete the fill, this can be borrowed from other college property, located north of the airport, to the rear of the Poultry Experimental Station. Drainage: The top soil is of sandy loam, and dark top soil, and is from six to eight inches deep. The subsoil is clay and sand down to a considerable depth. Drainage of the airport is accomplished by a joint system, catch basins and under- drains. The laterals are spaced 50 feet apart, and are laid at about a three-foot depth. The field will have a finished grade of .2%, eleping from the south and south- west to the north and northeast. Surfacing: Runways are located as shown on the enclosed plan, and are constructed of a penetration bituminous pavement. They are of a design and type recommended by the Michigan State Board of Aeronautics, and come under the Michigan State Highway Specifications as adopted on December 1, 1939. These specifications are 21A and 4.06. Aprons are of the same material. Parking lots are constructed of gravel. The entire airport, with the above exceptions, is seeded with a mixture of seeds, giving a firm.and Page 4 durable sod. The airport is to be enclosed with a good grade 5 feet fence. Lighting: Lighting equipment and installations of the airport con- forms with the suggestions set up by the Civil Aeronautics Authority. Boundary lights on marker cones are located 40 feet from the edge of the field at intervals of about 300 feet. Approach lights mark the end of each runway, and are epaced 50 feet apart. Obstruction lights are located on tOp of all buildings, and other obstacles within the airport. ”Obstruction lights are also placed on top of all obstacles outside the airport that are more than 70 feet high, and on all obstacles projecting above a glide angle of 20 to 1 from the end of the runway, a landing strip, or any obstruction which.is upstanding above adjacent objects, and is within one-half mile of the airport."* A ceiling projector is also installed. An airport beacon is located on top of the ad- mdnistration building. On top of the hanger is an illumin- ated wind direction indicator, with an obstruction light at itssuppermost point. General Airport Facilities: . There is to be a hangar with two side annexes, one for offices, the other a repair shop. It is constructed of sheet steel with doors at both ends opening the full width of the I hangar. The hangar is 100' I 60' x 18', and has a rounded roof. At the hanger there will be facilities for handling * See C.A.A. Bulletin Ho. 10 on Airport Lighting. Page 5 small repair Jobs. Fueling equipment is also available. Painted on t0p of the hangar will be the name of the airport and an arrow indicating north. The Administration building is a two story building of brick construction, and has available space for offices and radio equipment. At the present time electricity is being furnished to . this district, and, therefore, there is no additional eXpense for bringing electricity to the airport METEOROLOGICAL DATA (Taken from summary published by Weather Bureau Office, East Lansing, Michigan.)
