Achensee, Austria
Helicopter Accident, 2011
Achensee, Austria
In the morning of the 30th March 2011, an Austrian police helicopter of the type EC 135P2+ crashed into the lake of Achensee.
The accident report was recently published in November 2019, including the reconstruction of the overall flightpath as well as the visualization of the pilot’s perspective using the iwi® methodology.
The flight path of the helicopter was reconstructed in 2011, based on eyewitness information, being completed within a few days after the accident. The iwi® results could be confirmed with the lateron recovered FDR data, when the wreckage was retrieved from the lake.
As the last 9 seconds of the flight data recorder were incomplete, the eyewitness information was used to reconstruct the full flight path as well as the impact location of the helicopter in the lake.
To support the official investigation about human factors, the accident scenario was visualized with iwi® using latest Virtual-Reality technology, including laser scanned terrain (128 million points), high resolution aero images (0.25m), cockpit instrumentation and weather effects including water mirror effects.
The full iwi® report can be found in the official released accident report.
