Vibration of shock struts of an aircraft to relieve a portion of static friction forces acting on the shock struts before determination of aircraft weight and balance

A method comprising:

• receiving, at a computer system of an aircraft, a request to determine a weight of the aircraft, wherein the aircraft includes a plurality of landing gear and each landing gear of the plurality of landing gear includes a shock strut, wherein one or more excitation devices are coupled to each shock strut, and wherein the one or more excitation devices coupled to a particular shock strut are configured to vibrate the particular shock strut to enable the particular shock strut to transition from a first static state where an outer cylinder of the particular shock strut is stationary relative to an inner cylinder of the particular shock strut to a dynamic state where the outer cylinder moves relative to the inner cylinder and to transition from the dynamic state to a second static state;
• and
• causing, via the computer system in response to the request, one or more resonance systems to send first signals to the excitation devices to vibrate the shock struts.
