Missouri has 138 public-use airports, 111 of which are publicly owned.  Six are generally considered commercial passenger airports - Lambert-St. Louis International, Kansas City International, Springfield-Branson Regional, Columbia Regional, Cape Girardeau Regional and Joplin Regional.  The large air carrier airports that have at least 10,000 annual passengers were not included in this needs analysis.  They receive federal airport-improvement funding directly from the Federal Aviation Administration.  The aviation needs include maintenance and upgrades to physical facilities only, and do not include operational needs.  Existing airport facilities were compared with the standards for their respective classification.  Conditions where an airport did not meet standards were identified.  Deficiencies noted in past safety inspections also were represented as needs. Project needs for general aviation airports were developed in the three areas.  Pavement Runway protection zones, runway safety areas and navigational aids Terminal and landside projects Table 4 General Aviation Investment Goals (millions of dollars)   20-Year Capital Needs Aviation Rehabilitation and Reconstruction Expansion Cost to Achieve Desired Result Pavement $130 $100 $230 RPZ, RSA & Navaids $20 $20 $40 Terminal and Landside Projects $80 $60 $140         TOTAL $230 $180 $410 The aviation program's annual funding gap was forecast to be $11 million.  Almost half of this funding gap ($5 million) can be alleviated if the transfer of state sales tax on jet fuel to the aviation trust fund is extended beyond December 2003, when it is now scheduled to sunset.  While this aviation-user generated tax doesn't cover the entire funding gap, it allows MoDOT to make significant progress in meeting aviation needs. MoDOT supports continuation of the transfer of jet fuel sales tax revenue to the aviation trust fund. To ensure MoDOT will invest wisely in its aviation program, it will enact the following policies. MoDOT will work to restore and maintain the existing aviation system, provide a safe and reliable system that meets federal design criteria, and provide for expansion to meet future demand to allow for efficient and safe movement of people and goods.  MoDOT must make fiscally responsible decisions regarding investments in Missouri's aviation system. MoDOT will use its aviation prioritization process to allocate limited resources to maintain and enhance the aviation system.  MoDOT will develop partnerships with economic development agencies, other     governmental agencies, airport owners and other interested groups to promote and educate people about the importance of projects that facilitate growth of aviation facilities.
