A method for early detection of the vortex ring state in a helicopter includes steps of establishing flight control signals for flight control with regard to the vertical movement axis of the helicopter, detecting resultant movements in the vertical movement axis of the helicopter, and detecting an impending vortex ring state of the helicopter in accordance with a correlation between the flight control signals and the vertical movements in the vertical movement axis.

Early identification of a vortex ring phase

A method provides detecting a contact state between at least one driver/operator of a vehicle and a control input device designed to control the vehicle, where a frequency spectrum is calculated from sensors detected movement signals based on which the contact state between the control input device and the driver/operator is determined.
