What is the purpose of diagramming the wreckage and scene?

• A. To Communicate the Physical Relationships, Trajectories, and Impact Geometry Clearly and Reproducibly
• B. To Decorate the Report
• C. To Obscure Details from the Investigation
• D. To Replace Measurements with Drawings

Answer: (A)

Diagramming the wreckage and scene focuses on presenting the spatial relationships between pieces, flight path cues, and the geometry of the impact in a way that can be understood from the diagram alone and reproduced by others. In an aircraft mishap investigation, these drawings provide a clear map of where items lie, how they oriented on impact, and the trajectories debris followed, which helps reconstruct the sequence of events and validate findings. They complement measurements and photos to offer precise, scalable representations that anyone can interpret consistently, reducing ambiguity in the report. The diagrams are not decorative; they aren’t meant to obscure details, and they do not replace measurements with drawings. Instead, they enhance communication of the physical reality of the scene so conclusions are clear and verifiable.
