Helicopter Accident, 2018
Carcès, France
In the morning of the 2nd February 2018 two Helicopters (Gazelle SA 342 Ma) of the French Land Force took off from Le Luc, flying two independent missions. After eight minutes the helicopters collided over the lake of Carcès and crashed.
The iwi® methodology was applied to reconstruct and visualize the mid-air collision. The flight data of both helicopters could be reconstructed based on the following information:
The pilots-perspectives have been visualised using iwi® with Virtual-Reality technology, to support the accident-investigation and provide lessons-learned material.
The images below show the reconstructed flight path with the error tunnel, as well as the visualized pilots-perspectives shortly before the mid-air collision.
The iwi® methodology was applied to reconstruct and visualize the mid-air collision. The flight data of both helicopters could be reconstructed based on the following information:
- Radar data, but only partially available due to low-altitude
- Video information of surveillance camera recording one helicopter shortly before the mid-air
- Radio altimeter of both helicopters providing the altitude of the collision
- Impact-angle of the helicopters based on wreckage information
- Weather information and sun-position
