Flight Accident Investigation
The reconstruction of flight accident scenario is essential to determine the root causes. Flight recorder data, radar data and wreckage analysis can provide important indication.
However, in some accident cases, not all or even none of the before mentioned sources of information may be available.
Advanced Accident Reconstruction
If the accident scenario can not be reconstructed based on available information, additional potential sources like eyewitness statements or video recordings can be considered.
The world-wide unique method called Immersive-Witness-Interview (iwi®) was developed to use eyewitness statements and video information for flight path reconstruction.
The information is transferred in 3D environment with the software IWA. Flight path and aircraft attitude data are reconstructed based on available witness / video information.
The reconstructed flight path information considers potential error sources. The accuracy of the reconstruction is visualized by the error tunnel.
Witness and video information can be essential, if radar data is not complete or of insufficient accuracy due to terrain reflection.
In some accident cases witness information supported creating the overall accident scenario based on testimony information that was observed on board the aircraft.
The reconstructed accident scenario can become quickly complex and visualization can support to provide material for documentation and explanation, how the accident occurred.
Further more and more accidents are related to human factors. Therefore a photorealistic real-time visualization can support to better understand the accident scenario from different perspectives. Root causes like weather conditions, reaction time, diversion, etc. can be analyzed in Virtual-Reality environment.
The reconstructed flight path and the overall accident scenario including terrain and aircraft geometry are transferred into Virtual-Reality, providing real-time and photorealistic rendering with IWR.
This software can be used by authorities during the analysis of the accident sequence and dedicated scenes can be documented in the final report.
The integrated eyetracking technology allows detailed human factor analysis of accident sequence playback.
