Aircraft low pressure tire warning system having comparator circuit for each axle pair of a four wheel bogie configuration

摘要

An aircraft low tire pressure sensing and cockpit display and warning system utilizing axle wheel pair comparator circuitry to provide signals representative of pressures of the axle wheel pair less than a predetermined value, e.g. 15 percent less than a preset value determined by tire requirements or a difference between axle wheel pair pressures greater than a given value, e.g. 25 psi. In the event of tire master warning lamp illumination on the flight deck warning display, further push button interrogation and identification of the axle pair causing the warning can be made by a crew member on the flight deck warning display.
