A method of monitoring a gas turbine engine includes the steps of: (a) receiving information from actual flights of an aircraft including an engine to be monitored, and including at least one of the ambient temperature at takeoff, and internal engine pressures, temperatures and speeds; (b) evaluating the damage accumulated on an engine component given the data received in step (a); (c) storing the determined damage from step (b); (d) repeating steps (a)-(c); (e) recommending a suggested future use for the component based upon steps (a)-(d). A system is also disclosed.

1. A method of monitoring a gas turbine engine comprising the steps of: (a) receiving information from actual flights of an aircraft including an engine to be monitored, and including at least one of the ambient temperature at takeoff, and internal engine pressures, temperatures and speeds;(b) evaluating the damage accumulated on an engine component given the information received in step (a);(c) storing the determined damage from step (b);(d) repeating steps (a)(c);(e) recommending a suggested future use for the component based upon steps (a)(d);wherein the recommended future use includes a suggestion to utilize a particular component or engine on a particular type flight, and said particular type flight being distinct from a prior type flight through which steps (a)-(d) occurred. 2. The method as set forth in claim 1, wherein the information received at step (a) is received remotely at a ground-based evaluation location. 3. The method as set forth in claim 2, wherein the information is streamed off of the aircraft to the ground-based location. 4. The method as set forth in claim 2, wherein the information is recorded substantially continuously during a flight onboard the aircraft, and received from the aircraft at a later time. 5. The method as set forth in claim 1, wherein the particular type flight is on an engine having a different thrust rating than a current use of the component. 6. The method as set forth in claim 1, wherein the particular flight is for use on an aircraft flying routes having a distinctly different ambient temperature than current use. 7. The method as set forth in claim 1, wherein a component other than the component being monitored is evaluated along with the component being monitored to identify the suggested future use. 8. The method as set forth in claim 1, wherein the storing of step (c) is supplemented to provide information on missing flight information. 9. The method as set forth in claim 8, wherein the supplementation is provided by a conservative nominal predicted cycle. 10. The method as set forth in claim 1, wherein actual flight data information is evaluated to develop algorithms that can then be utilized at step (b) to predict the actual damage accumulated on said component being monitored. 11. The method as set forth in claim 1, wherein a maintenance facility receives the suggested future use and takes an action on the component. 12. The method as set forth in claim 11, wherein the action is reported back to be stored and utilized at least in step (e). 13. The method as set forth in claim 1, wherein steps (a)-(e) are performed on an aircraft including the engine being monitored. 14. The method as set forth in claim 1, wherein the engine component is an engine life limited part. 15. The method as set forth in claim 1, wherein the suggested future use is transmitted to a maintenance facility. 16. A system comprising: a ground-based evaluation system programmed to perform the following steps: (a) receiving information from actual flights of an aircraft including an engine to be monitored, and including at least one of the ambient temperature at takeoff, and internal engine pressures, temperatures and speeds;(b) evaluating the damage accumulated on an engine component given the information received in step (a);(c) storing the determined damage from step (b);(d) repeating steps (a)-(c);(e) recommending a suggested future use for the component based upon steps (a)-(d);wherein the recommended future use includes a suggestion to utilize a particular component or engine on a particular type flight, and said particular type flight being distinct from a prior type flight through which steps (a)-(d) occurred. 17. The system as set forth in claim 16, wherein a component other than the component being monitored is evaluated along with the component being monitored to identify the suggested future use. 18. The system as set forth in claim 16, wherein actual flight data information is evaluated to develop algorithms that can then be utilized at step (b) to predict the actual damage accumulated on each particular component being monitored. 19. The system as set forth in claim 16, wherein an action taken based upon the suggested future use is reported to the ground-based evaluation system, stored and used at least in performing step (e). 20. The system as set forth in claim 16, wherein steps (a)-(e) are performed on an aircraft including the engine being monitored. 21. The system as set forth in claim 16, wherein the engine component is an engine life limited part. 22. The system as set forth in claim 16, wherein said evaluation system is ground based. 23. The system as set forth in claim 16, wherein the suggested future use is transmitted to a maintenance facility. 24. The method as set forth in claim 5, wherein the particular type flight is also for use on an aircraft flying routes having a distinctly different ambient temperature than current use. 25. The method as set forth in claim 16, wherein the particular type flight is on an engine having a different thrust rating than a current use of the component. 26. The method as set forth in claim 25, wherein the particular type flight is also for use on an aircraft flying routes having a distinctly different ambient temperature than current use. 27. The method as set forth in claim 16, wherein the particular type flight is for use on an aircraft flying routes having a distinctly different ambient temperature than current use.
