A system and method include a hydraulic system onboard an aircraft, a first temperature sensor, a second temperature sensor, and a controller. The first temperature sensor measures a first temperature of hydraulic fluid upstream of an inlet of a pump of the hydraulic system. The second temperature sensor measures a second temperature of the hydraulic fluid within a cooling flow stream downstream of an outlet of the pump. The controller determines a value of a temperature rise of the hydraulic fluid across the pump as a difference between the first temperature and the second temperature, and obtains an expected range for the temperature rise across the pump based on a speed of the pump. In response to the value of the temperature rise being outside of the expected range, the controller generates a maintenance message for communication off-board the aircraft, indicating the pump is degraded.
