A method of determining whether a landing event of an aircraft is hard may comprise: receiving, by a controller (230) via a stroke position sensor (116), a stroke profile as a function of time for a shock strut; receiving, by the controller via a gas pressure sensor (110), a gas pressure in a gas chamber of the shock strut; receiving, by the controller via a wheel speed sensor (120), a wheel speed of a tire in a landing gear assembly; calculating, by the controller, multiple time dependent functions based on the stroke profile of the shock strut, based on the gas pressure, a shock strut temperature, and the wheel speed; and comparing, by the controller, the multiple time dependent functions to respective predetermined thresholds to determine whether the landing event is hard.
