This noise analysis was prepared as a part of the OSU Airport Master Plan Update (MPU) project. The FAA’s Aviation Environmental Design Tool version 2d (AEDT 2d) was used to develop the DNL contours for this project. The DNL contours were prepared using the forecasted aircraft activity for the OSU MPU. A detailed discussion of the model inputs used to develop these contours is included in the following sections. 2.0 2037 Forecasted Aircraft Operations The number of 2037 aircraft operations was forecasted to be 112,000, which was broken into 66,100 itinerant operations and 45,900 local operations. The definition of the local operation is aircraft operations that stays the traffic pattern known as touch-and-go operations. Itinerant operations mean aircraft operations other than local operations. 3.0 Aircraft Fleet Mix The MPU forecast provided a comprehensive list of aircraft that are expected to utilize OSU for in calendar year 2037. This list was used to determine equivalent AEDT aircraft for the purposes of developing DNL contours. In determining the AEDT equivalent aircraft for the purposes of noise modeling, research was conducted by aircraft type to determine the specific airframe, engine codes, and engine modification codes of the expected 2037 aircraft fleet. The AEDT fleet mix was developed and is presented in Appendix A . 4.0 Stage Lengths Once the specific fleet mix was completed, departure destination information was analyzed to determine departure stage lengths. An aircraft’s stage length (or trip length) refers to the distance an aircraft flies from its origin airport (OSU) to its intended destination. Stage length is important in noise modeling since the longer the distance an aircraft will fly to its destination, the greater the fuel load required and overall weight and, as a result, the lower its departure profile will be. Stage lengths used in the AEDT include the following stages: The Ohio State University Airport ESA / Project No. 160608.00 Master Plan Update Noise Contour Development 1 November 2018 The Ohio State University Airport Stage Length 1: 0 to 500 miles Stage Length 2: 500 to 1,000 miles Stage Length 3: 1,001 to 1,500 miles Stage Length 4: 1,501 to 2,500 miles Stage Length 5: 2,501 to 3,500 miles Stage Length 6: 3,501 to 4,500 miles Stage Length 7: 4,501 to 5,500 miles Stage Length 8: 5,501 to 6,500 miles Stage Length 9: 6,500+ miles Three aircraft were identified other than the Stage Length of 1. All of Bombardier Global 5000 Business and Bombardier Global Express were modeled as Stage Length 3 and 2, respectively. 97.5% of Eclipse 500 were modeled as Stage Length 2, while 2.5% of Eclipse 500 were modeled as Stage Length 1. 5.0 Time of Day Another important component in developing the DNL contours is determining the day-night use percentages for each AEDT aircraft. This data is important because the DNL metric is a 24-hour, time-weighted energy average. The time-weighting refers to the fact that noise events occurring during certain noise sensitive time periods receive a penalty. For the DNL metric, noise events occurring between the hours of 10:00:00 p.m. and 6:59:59 a.m. receive a 10-dB “penalty”. This penalty attempts to account for the higher sensitivity to noise in the nighttime and the expected decrease in background noise levels at night in comparison with background noise levels during the day. Because noise is measured on a logarithmic scale, a 10-dB penalty means each nighttime noise
