A method of predicting a fault in an air-conditioning pack of an aircraft is disclosed. The air-conditioning pack includes one or more sensors outputting data related to air-conditioning pack temperature, air-conditioning pack pressure, or air-conditioning pack valve or actuator positions. The method includes transmitting data from at least one of the sensors operably coupled to the air-conditioning pack, comparing the transmitted data to a predetermined threshold, and predicting a fault in the air-conditioning pack based thereon.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method of predicting a fault in an air-conditioning pack of an aircraft, wherein the air-conditioning pack includes one or more sensors outputting data related to air-conditioning pack temperature, air-conditioning pack pressure, or air-conditioning pack valve or actuator position, the method comprising: transmitting data output from at least one of the sensors, wherein the sensors are operably coupled to the air-conditioning pack; comparing, by a controller, the transmitted data to a predetermined threshold; predicting a fault in the air-conditioning pack based on the comparison; and providing an indication of the predicted fault. 2. The method of claim 1, wherein transmitting the data comprises transmitting data related to a pre-flight and a cruise segment of a flight. 3. The method of claim 1, wherein transmitting the data comprises transmitting data from a plurality of flights. 4. The method of claim 3, wherein comparing the transmitted data comprises comparing the data from the plurality of flights with the at least one predetermined threshold. 5. The method of claim 4, wherein predicting the fault comprises predicting the fault when comparisons indicate the predetermined thresholds are satisfied over multiple flights. 6. The method of claim 1, wherein a controller of the aircraft compares the transmitted data, predicts the fault, and provides the indication of the predicted fault. 7. The method of claim 6, wherein the controller utilizes an algorithm to predict the fault. 8. The method of claim 1, wherein the transmitted data is indicative of temperatures, pressures, valve positions, and actuator positions of the air-conditioning pack. 9. The method of claim 8, wherein the comparing comprises comparing the temperatures, pressures, and positions to corresponding predetermined thresholds. 10. The method of claim 8, further comprising calculating median values for the transmitted data. 11. The method of claim 10, wherein the comparison comprises comparing the median value to the predetermined threshold. 12. The method of claim 8, further comprising calculating minimums and maximums for the transmitted data. 13. The method of claim 12, wherein the comparison comprises comparing the minimums or maximums to the predetermined thresholds. 14. The method of claim 1, further comprising monitoring, with one or more sensors, additional features including bleed air temperature, bleed air pressure, bypass valve position, and outside air temperature. 15. The method of claim 14, wherein the fault is predicted with a heat exchanger of the air-conditioning pack when it is determined the additional features are within normal ranges. 16. The method of claim 2, wherein transmitting the data comprises transmitting data from a plurality of flights. 17. The method of claim 9, further comprising calculating median values for the transmitted data. 18. The method of claim 9, further comprising calculating minimums and maximums for the transmitted data. 19. The method of claim 10, further comprising calculating minimums and maximums for the transmitted data. 20. The method of claim 11, further comprising calculating minimums and maximums for the transmitted data.
