General Aviation (GA) weather related accidents have steadily remained the most fatal accidents and incidents in the GA flight community. The majority of these accidents involve low-experienced Visual Flight Rule (VFR) pilots who inadvertently encounter Instrument Meteorological Conditions (IMC). Additional concerns include pilots’ encountering Convective Weather/Thunderstorms during flight. The purpose of the General Aviation Weather Project is to mitigate the risk of these incidents by conducting research on aviation weather display interpretability and the implications for general aviation pilot training. This project includes the development and validation of aviation weather information and display interpretation questions, research on pilot weather training methods and measures, as well as weather related performance support tools for GA pilots.
