A method, medium, and system to receive actual operational flight data for an engine of a particular type and configuration; train a neural network to generate an indicator of the health of the engine based on multiple different inputs to the neural network at a time the flight data was acquired; determine a deterioration factor for the engine, based at least in part, on an operational climate for the engine; and provide a record of the determined deterioration factor.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method, the method comprising: receiving actual operation flight data for an engine of a particular type and configuration; training a neural network to generate an indicator of the health of the engine based on multiple different inputs to the neural network at a time the flight data was acquired; determining a deterioration factor for the engine, based at least in part, on an operational climate for the engine; and providing a record of the determined deterioration factor. 2. The method of claim 1, wherein the engine comprises a high-bypass turbofan engine. 3. The method of claim 1, wherein the health of the engine is indicated by an exhaust gas temperature parameter for the engine. 4. The method of claim 1, wherein the multiple different inputs to the neural network include at least a bleed ratio, a Mach number, a percentage of maximum fan speed of the engine, ambient temperature, and altitude. 5. The method of claim 1, wherein the climate is determined to be at least one of the following different climates: tropical/equatorial, dry, mild temperate, continental/microthermal, and polar. 6. The method of claim 1, wherein the deterioration factor is determined on a basis of an airline operator. 7. A non-transitory medium storing processor-executable program instructions, the medium comprising program instructions executable by a computer to: receive actual operation flight data for an engine of a particular type and configuration; train a neural network to generate an indicator of the health of the engine based on multiple different inputs to the neural network at a time the flight data was acquired; determine a deterioration factor for the engine based, at least in part, on an operational climate for the engine; and provide a record of the determined deterioration factor. 8. The medium of claim 7, wherein the engine comprises a high-bypass turbofan engine. 9. The medium of claim 7, wherein the health of the engine is indicated by an exhaust gas temperature parameter for the engine. 10. The medium of claim 7, wherein the multiple different inputs to the neural network include at least a bleed ratio, a Mach number, a percentage of maximum fan speed of the engine, ambient temperature, and altitude. 11. The medium of claim 7, wherein the climate is determined to be at least one of the following different climates: tropical/equatorial, dry, mild temperate, continental/microthermal, and polar. 12. The medium of claim 7, wherein the deterioration factor is determined on a basis of an airline operator. 13. A system comprising: a computing device comprising: a memory storing processor-executable program instructions; and a processor to execute the processor-executable program instructions to cause the computing device to: receive actual operational flight data for an engine of a particular type and configuration; train a neural network to generate an indicator of the health of the engine based on multiple different inputs to the neural network at a time the flight data was acquired; determine a deterioration factor for the engine, based at least in part, on an operational climate for the engine; and provide a record of the determined deterioration factor. 14. The system of claim 13, wherein the engine comprises a high-bypass turbofan engine. 15. The system of claim 13, wherein the health of the engine is indicated by an exhaust gas temperature parameter for the engine. 16. The system of claim 13, wherein the multiple different inputs to the neural network include at least a bleed ratio, a Mach number, a percentage of maximum fan speed of the engine, ambient temperature, and altitude. 17. The system of claim 13, wherein the climate is determined to be at least one of the following different climates: tropical/equatorial, dry, mild temperate, continental/microthermal, and polar. 18. The system of claim 13, wherein the deterioration factor is determined on a basis of an airline operator.
