Despite all of the advancements in aviation that have occurred in the last century, aircraft still occasionally collide with terrain. The purpose of my project is to discover the errors that exist in current iterations of terrain avoidance and warning software (TAWS) and potential remedies for said issues. My research is conducted through the analysis of post-accident reports compiled by the National Transportation Safety Board (NTSB), software testing conducted at ACSS, and software experimentation within a King Air aircraft. What my research has currently led me to conclude is that nuisance alerts are the leading cause for controlled flight into terrain accidents (CFIT). Once the errors in the TAWS software are brought to light, then hopefully any problems can be solved. Hopefully, these solutions would result in fewer preventable deaths.
