capacity would be increased from 230,000 to 355,000 annual operations with • the addition of a parallel runway; as estimated 43 based aircraft would still need to be diverted from Anoka County-Blaine. This estimate is based on Anoka County-Blaine diverting aircraft until it reaches 80 percent of its operational capacity. As in all diversion scenarios, 55 single- and light twin- engine aircraft would be diverted from St. Paul Downtown to Lake Elmo. While a new general aviation airport could attract some aircraft and operations from Crystal Airport, Crystal's demand is not projected to reach 80 percent of ASV by the end of the planning period. Therefore, significant diversion from Crystal is unlikely unless the new facility is located in close proximity to Crystal. Also, some diversion from Flying Cloud to a new airport could also occur; however, most of Search Area "A" is located beyond the 15- mile limit for attracting diverted aircraft from Flying Cloud. Therefore, significant diversion from Flying Cloud is not expected. To date, a specific area and public sponsor for the new general aviation airport have not been identified. 2. Operational Demand A new airport, operating at 80 percent of as estimated ASV of 230,000 operations, would be able to accommodate approximately 294 based aircraft. With diversion from Anoka County-Blaine (29,000 operations), the new, general aviation airport would reach only 13 percent of its operational capactty by the end of the planning period, assuming 43 aircraft from Anoka County- Blaine would be based at the new airport. This will provide enhanced potential for continued growth of the reliever system beyond the planning period. In all likelihood, a new airport located in Search Area "A" would also attract aircraft currently based at Flying Cloud and/or Crystal airports. The actual number of aircraft attracted from these two airports would depend on the location of the new airport in relation to the location of the aircraft owners. With Alternative 8, all relievers will be operating at approximately 80 percent or less of their operational capacity. The projected number of annual operations as a percentage of ASV for each of the relievers in Alternative 8 is presented in Table N il. 3. System Delay By the end of the planning period, total reliever system delay for Alternative 8 is estimated at 1.4 million minutes annually. Average delay per aircraft operation by the end of the planning period is estimated at one minute. Four of the eight relievers in Alternative 8 are estimated to approach 80 percent of thew operational capacity. These four relievers, Anoka County- Blaine, Crystal, Flying Cloud, and SG Paul Downtown, would have an average of 1.2 minutes of delay per operation. The new general aviation airport in N-45
