A dynamic 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 combined to generate signals representing the weight carried by the structural member. When the aircraft is moving, the weight signal is analyzed to determine whether particular frequency components are present therein. The amplitude of these frequency components are modified by a gain factor dependent upon a reference amplitude and are added to develop a tire pressure signal. The tire pressure signal is compared against a trip setting to determine whether the tire pressure is within acceptable limits. If the tire pressure is outside of the range of acceptable tire pressures, a signal is generated to warn of a potentially dangerous condition to the aircraft operating personnel. |
