The primary users to be accommo- <br />dated at these facilities are the air carriers <br />(scheduled, commuter and supplemental). <br />Intermediate <br />The primary geographic/service focus of airports <br />in this category would be national, state and <br />metropolitan in scope. The primary users to be <br />accommodated at these facilities would be <br />corporations. <br />Minor <br />The primary geographic/service focus of airports <br />in this category would be state and metropolitan <br />in scope. Personal, business and instructional <br />uses would be accommodated at these facilities. <br />Special Purpose <br />The primary geographic/service focus of airports <br />in this category would be state and metropolitan <br />in scope. Personal. business. military and instruc- <br />tional uses would be accommodated at these <br />facilities. <br />How the new functional classification system of <br />airports compares to existing state and federal <br />classifications is shown in Table 3. <br />Source: Aviation Chapter/Development Guide <br />iA/4/78 <br />2—A <br />
