Abstract: A method, apparatus, and system for managing a supplemental cooling unit. The process receives data for a supplemental cooling unit. The data comprises a pressure, a temperature, and a speed. The process generates a set of alerts based on the data for the supplemental cooling unit and a signature in the data.

Abstract: In an example, a method for on-board maintenance of an aircraft is described. The method includes measuring, by a pressure sensor, a pressure in a tube associated with an engine of an aircraft. The method also includes determining, by a control system and based on the pressure measured by the pressure sensor, that the tube is at least partially blocked by moisture. Additionally, the method includes, responsive to determining that the tube is at least partially blocked by the moisture, providing an alert signal from the control system to a flight deck of the aircraft. The method also includes, responsive to the alert signal, operating an actuation switch at the flight deck to actuate a valve to an open state. The method further includes, responsive to actuating the valve to the open state, supplying an inert gas from an inert gas supply to the tube to expel the moisture.

Abstract: Aspects of the present disclosure provide a method and apparatus for predicting noncompliance conditions of rotating machinery in aerial vehicles. Embodiments include receiving records related to historical noncompliance conditions of a plurality of rotating machines. The records include deceleration time values related to the plurality of rotating machines. Embodiments include generating, based at least on the deceleration time values and the historical noncompliance conditions, a predictive model. Embodiments include receiving sensor data related to a rotating machine of an aerial vehicle. Embodiments include determining, based on the sensor data, a series of deceleration time values for the rotating machine. Embodiments include using the predictive model to determine whether a noncompliance condition is predicted to occur for the rotating machine based on the series of deceleration time values.
