This thesis outlines the creation of an excel tool designed to utilize public flight data for a given flight and determine further information such as general flight properties, weight estimation, and aerodynamic and stability characteristics. In depth analyses is done for a TV Relay flight of a Beechcraft Super King Air 200 to display the data processing and accuracy of the values. From this analyses it is displayed that the aircraft is flown safely and well within its performance parameters for the entire mission. The usefulness of this tool comes from its ability to successfully analyze critical properties and perform pilot and crash reconstruction analysis.
