Abstract: A method, system, and device for predicting parachuting time in case of a sudden failure are provided to resolve a prior art problem that parachuting time of a parachutist in case of a sudden failure of an aircraft cannot be predicted accurately and efficiently. The method includes: obtaining input data; preprocessing the input data; determining whether an aircraft is in a sudden failure state; generating a movement track and a landing point range of parachuting; calculating a movement track and a falling point range of the aircraft after a parachutist performs parachuting, and impact force and a damage range after the aircraft falls; and obtaining a prediction result of parachuting time of the parachutist by a pre-constructed parachuting time prediction model. The method, system, and device can accurately and efficiently predict the parachuting time of the parachutist in case of the sudden failure of the aircraft.
