Welcome to the "Preflighting the Beechcraft Sundowner" web site. This site contains information about a computer-based training program that has been developed at the Institute of Aviation (University of Illinois at Urbana-Champaign). The program was created using Multimedia ToolBook (a PC-based Multimedia development tool by Asymetrix Corp.).
