PROGNOSTICS FOR PRESSURE SENSORS OF HYDRAULIC BRAKE SYSTEMS

A method of performing prognostics on a hydraulic brake system of an aircraft may include determining, during primary braking mode and by a hydraulic brake controller, a first status of a first brake pressure sensor adjacent a brake assembly. The method may also include, in response to determining that the first status of the first brake pressure sensor is valid, determining, during park braking mode and by the hydraulic brake controller, a second status of a second brake pressure sensor adjacent a park valve assembly. In response to determining that the first status of the first brake pressure sensor is degraded, the method may include outputting, by the hydraulic brake controller, at least one of an inspection indicator and a maintenance indicator.
