US Patent 10474237 Haptic feedback for rotary wing aircraft

A method for providing haptic feedback to a user of a rotary wing aircraft that includes receiving, by a computing device, a signal indicative of a user input selecting a control system state for a rotary wing aircraft, where, upon selection, the control system state modifies one or more operational parameters of the rotary wing aircraft, and in response to receiving the signal, outputting, by the computing device, a signal to a shaker system coupled to a collective stick, where the signal is configured to cause the shaker system to provide a haptic feedback via the collective stick, and where the haptic feedback includes a signature that indicates that the control system state has been activated.
