What is it about?
Helicopter roll may force the pilot to unintentionally move the control stick in a manner that further excites the roll motion. We numerically simulated and verified this in the flight simulator.

Why is it important?
The phenomenon was studied, simulated, and experimentally reproduced in the flight simulator using accurate numerical models and skilled test pilots. Some helicopters may be particularly susceptible to the problem. In the future, the spread of flight control systems and automation may cause its insurgence, unless its possibility is detected and prevented by design.
Perspectives
In this work, I had the opportunity to work with test pilots. Understanding their behavior, and trying to capture and model it for predicting the pilot-vehicle system behavior was a challenge and a great opportunity to improve my knowledge, my skills, and to open my mind to new problems.
