Abstract
A weight and balance system for an aircraft or the like which measures the bend in a structural member of the aircraft, such as a landing gear element or a wing or fuselage section, by use of inclinometers mounted to the member and each having a signal output representing the angle of the member with respect to a reference plane and then summing signal outputs from the incinometers to determine the angle of the bend which provides an indication of weight. In one example, the landing gear of the aircraft includes a member which bends in response to aircraft weight and a pair of inclinometers, in the form of servoed accelerometers, are mounted to the member adjacent opposite ends thereof and each provide a voltage output representing the angle of the member relative to the reference plane, and a summing device for summing said signal outputs as an indication of weight. For tire pressure detection, a plurality of inclinometers are associated with a bogie beam to determine which one of two or more pairs of tires is underpressured.
