Abstract
Aircraft accident forensics include analyzing cockpit voice recorder (CVR) and flight data recorder (FDR) information. Each recorder is independent of the other and often share no common time frame. Analysts must align the two time scales using common events on each recorder, such as microphone keying events. Using test drive development and linear programming, we have created a two-step model to align the CVR and FDR recordings. The first linear model matches microphone keying events, while the second linear model optimizes alignment of the time scales. When the constrained optimization problem produces a feasible solution, a standardized computer-generated sentence is created that is useful for forensic reporting purposes.
