Therefore, <br />the engineer will be concerned with the volume of itinerant operations at <br />nontower airports. <br />The above Figure 9-2, provides a guide for estimating the number of annual <br />itinerant operations per based airplanes. The chart indicates a range from <br />120 to 450 operations at nontower airports, the normal is 210. <br />The design engineer may determine, for example, that an above average <br />activity is expected at the proposed airport and 250 is selected as the <br />estimated number of itinerant operations. Assuming the number of airplanes <br />forecast to be based at the airport within two years is 20, the total <br />estimated annual itinerant operations would be 250 x 20, or 5,000. <br />FIGURE 9-2.
