The present invention relates to a method (900) for protecting a rotorcraft from entering a vortex ring state. The method (900) comprises: monitoring (902) a vertical speed and a forward speed of a rotorcraft; determining (908) whether to perform vortex ring state (VRS) avoidance according to at least one of the vertical speed and the forward airspeed of the rotorcraft; and performing (912, 914), in response to determining to perform the VRS avoidance, control of one or more flight parameters of the rotorcraft. Also disclosed are a device configured to carry out the method (900) and a rotorcraft comprising a flight control computer configured to carry out the method (900).
