Abstract

A method for optimizing data gathering, is provided wherein the method comprising the steps of designing a first system test comprising two or more maneuvers, compiling a one or more data variable for each of the two or more maneuvers from the first system test, pooling each data variable from each maneuvers into a first set of data, removing a first maneuver'"'"'s data variables from the pooled first set of data, comparing the first maneuver'"'"'s data variables against the first set of data with the first maneuver'"'"'s data variables removed, and determining whether to perform the first maneuver based on whether the maneuver provided new data.

Claims

1. A computer implemented method for optimizing data gathering, the method comprising the steps of:

designing a first system test of two or more maneuvers;

compiling a one or more data variable for each of the two or more maneuvers from the first system test;

pooling each data variable from each maneuver into a first set of data;

removing a first maneuver'"'"'s data variables from the pooled first set of data;

comparing the first maneuver'"'"'s data variables against the first set of data with the first maneuver'"'"'s data variables removed; and

determining whether to perform the first maneuver based on whether the maneuver provided new data and storing the result.

2. The method is claim 1 further comprising the steps of:

simulating the first system test by simulating each of the two or more maneuvers; and

using the simulation to calculate each one or more data variable for each of the one or more maneuver.

3. The method of claim 1 further comprising the step of removing the first maneuver from the first system test if the maneuver provided no new data.

4. The method of claim 3 further comprising the steps of:

removing a next successive maneuver'"'"'s data variables from the pooled first set of data;

comparing the next successive maneuver'"'"'s data variables against the first set of data with the next successive maneuver'"'"'s data variables removed; and

determining whether to perform the next successive maneuver based on whether the next successive prearranged maneuver provided new data.

5. The method of claim 4 further comprising the step of removing the next successive maneuver from the first system test if the next successive maneuver provided no new data.

6. The method of claim 1 further comprising the steps of:

normalizing the pooled first set of data; and

determining a variance of a first maneuver data'"'"'s from the normalized first set of data.

7. The method of claim 6 further comprising the step of establishing a predetermined set point, whereby if the variance exceeds the set point, the first maneuver variable data is considered new data.

8. The method of claim 1 wherein the first system test is a flight test.

9. The method of claim 1, wherein the comparing step further comprises the step of using the MSET algorithm.

10. The method of claim 1 wherein the comparing step further comprises the step of using a pattern recognition algorithm analysis to determine if the maneuver'"'"'s variable data varies from the first set of data.

11. A computer implemented method for optimizing data gathering, the method comprising the steps of:

performing a first system test;

compiling a first set of test data from the first system test;

designing a second system test;

designing a series of one or more maneuvers for the second system test;

performing each one or more maneuvers as part of the second system test; and

compiling a one or more data variable from each of the one or more maneuvers,

compiling a second set of test data from the second system test;

comparing the first data set to the second data set;

determining whether to perform the second test based on the comparing step;

comparing a first maneuver'"'"'s data variables against the first set of data; and

determining whether to perform the first maneuver based on whether the maneuver provided new data and storing the result.

13. The method of claim 11 further comprising the steps of:

removing the first maneuver from the second system test if the maneuver provided no new data;

comparing a next successive maneuver'"'"'s data variables against the first set of data; and

determining whether to perform the next successive maneuver based on whether the next successive maneuver provided new data.

14. The method of claim 11, wherein the first system test is a flight test.

15. The method of claim 11, wherein the comparing step further comprises the step of using the MSET algorithm.

16. The method of claim 11, wherein the comparing step further comprises the step of using statistically analysis to determine if the second set of prearranged maneuver'"'"'s variable data varies from the first set of data.

12. A computer implemented method for optimizing data gathering, the method comprising the steps of:

performing a first system test;

compiling a first set of test data from the first system test;

designing a second system test;

designing a series of one or more maneuvers for the second system test;

performing each one or more maneuvers as part of the second system test;

compiling a one or more data variable from each of the one or more maneuvers,

compiling a second set of test data from the second system test;

comparing the first data set to the second data set;

determining whether to perform the second test based on the comparing step;

simulating the second system test by simulating each one or more maneuver; and

calculating each one or more data variable for each of the one or more simulated maneuver and storing the result.
