This report answers the following questions about airports' capital development projects: (1) How much are airports of various sizes spending on capital development and where is the money coming from? (2) If current funding levels continue, will they be sufficient to meet capital development planned for the 5-year period from 1997 through 2001?; and (3) If a difference exists between current funding and planned development, what is the potential effect of various proposals to increase airport funding? Includes testimony by Gerald Dillingham, Assoc. Director, Transportation Issues, Resources, Community, and Economic Development Div., General Accounting Office.
