1998 NTSB TWA800 VIS LAB SIMULATION https://www.youtube…

- - - - Animation has gone past the point where aircraft exploded. Allows for a complete event understanding
      - Has accounted for the wreckage getting down to the water.
- - - - Change of Legislation if needed
      - Issuance of engineering instructions
      - Issuance of recomendations
    - - Part of a complete investigation.
      - Simulation matches data evidence
    - - Implementation of findings
    - - Flying confidence returned
    - - Re-design and re-engineering of faulty parts
  - - - YES. ATSB is authorative
      - YES. Approved by ATSB.
    - - Tool needs independent varification
  - - - Can causation be identified?
        
        Not identifiable from this simulation
- - - - Flight performance software
      - Three, four and six degrees of freedom
  - - - All NTSB data sent to Engineering Animation
    - - Vis Lab animation software
        
        Important text information added
        
        Picture in picture display created
        
        Camera positions determined
        
        Special effect added
      - NTSB data pairing
      - 3D animation specialists
  - - - Algorithms supplied by Boeing
    - - Raw digital data converted into useful info
      - High speed machines
    - - 17 parameters recorded once per second
        
        Time history files created
        
        Parameter examples
        
        Airspeed
        
        Pitch
        
        Altitude
        
        Roll
        
        Vertical acceleration
        
        Lateral acceleration
        
        8 samples per second
        
        Each individual parameter charted
- - - - Simulation is frame by frame, 30-60 frames per second
  - - - Not as accurate as FDR data
      - Trajectory analysis tried a couple of ways to fit data
        
        Tried to fit the aerodynamics to match radar data
