TSB raising the bar on safety: Reducing the risks that persist in commercial helicopter operations
This led to an unexpected loss of visual reference to the horizon, also known as inadvertent flight into instrument meteorological conditions (inadvertent IMC).
- This led to an unexpected loss of visual reference to the horizon, also known as inadvertent flight into instrument meteorological conditions (inadvertent IMC).
- While the pilot was likely attempting to visually manoeuvre the helicopter in response to inadvertent flight into IMC, an unintentional descent resulted in the helicopter colliding with terrain.
- "For more than 30 years, the TSB has been calling for the implementation of safety measures to mitigate the risks that persist in helicopter reduced visibility operations.''

require commercial helicopter operators to implement technology that will assist pilots with the avoidance of, and recovery from, inadvertent flight into IMC.
