ABSTRACT:
A static low tire pressure detection system for detecting the presence of a low tire mounted on a structural member of an aircraft, such as a bogie beam or nose axle, includes a pair of inclinometers mounted on the structural member and adapted to sense the bend therein. The signals from the inclinometers are stored in a memory once the aircraft is at rest on the ground to provide reference signals indicating the angle of the structural member with respect to an inertial reference and the weight carried thereby. The reference signals are compared against later-developed signals representing instantaneous angle and weight on the structural member to develop difference signals. The difference signals are used to generate an indication of tire pressurization, which is then checked to determine whether the tire pressurization is within acceptable limits. If the tire pressure is outside of the acceptable limits, then an indicating device is energized to provide a warning of a potentially dangerous condition to the aircraft operating personnel.
