The methods and systems provide for increasing the accuracy of aircraft weight and center of gravity determination through the use of filtered strut pressure measurements. Aircraft vertical and horizontal accelerations are determined as the aircraft is taxiing, and used to identify and reduce the number of significantly distorted pressure measurements, to allow the lesser distorted pressure measurements to be averaged, and a lesser number of distorted pressure measurements to be averaged; further identifying the aircraft in near-neutral acceleration and strut pressure values near-neutral of strut seal friction distortions. Pressure sensors, accelerometers, and an inclinometer are mounted in relation to landing gear struts to monitor, measure and record strut pressure as related to strut telescopic movement, rates of strut telescopic movement and aircraft vertical and horizontal accelerations; experienced by landing gear struts, as the aircraft proceeds through typical ground and taxi operations.
