<p>An onboard system for use in measuring, computing and displaying the gross weight and location of the center of gravity of an aircraft (1) is disclosed. Temperature and pressure sensors are mounted in communication with each of the landing gear struts (3, 5, 7). The resulting temperature and pressure signals are transmitted to an onboard computer (25) for processing the signals to derive the weight and center of gravity. The computer also includes redundancy for accuracy and failure protection, software to compensate for changes in the struts, software to adjust the output data for prevailing temperature and strut friction conditions, and a program to illuminate a 'HARD LANDING' warning indicator.</p> |
