Appendix 6 to AMC1 FSTD(H).300 Recurrent evaluations – validation test data presentation Decision 2012/011/R (a) Background (1) During the initial evaluation of an FSTD the MQTG is created. This is the master document, as amended, to which FSTD recurrent evaluation test results are compared. (2) The currently accepted method of presenting recurrent evaluation test results is to provide FSTD results over-plotted with reference data. Test results are carefully reviewed to determine if the test is within the specified tolerances. This can be a time consuming process, particularly when reference data exhibits rapid variations or an apparent anomaly requiring engineering judgement in the application of the tolerances. In these cases the solution is to compare the results to the MQTG. If the recurrent results are the same as those in the MQTG, the test is accepted. Both the FSTD operator and the competent authority are looking for any change in the FSTD performance since initial qualification. (b) Recurrent evaluation test results presentation (1) To promote a more efficient recurrent evaluation, FSTD operators are encouraged to over-plot recurrent validation test results with MQTG FSTD results recorded during the initial evaluation and as amended. Any change in a validation test will be readily apparent. In addition to plotting recurrent validation test and MQTG results, operators may elect to plot reference data as well. (2) For full flight simulators (FFSs) and flight training devices (FTDs: when tests are not based on CT&M) there are no suggested tolerances between the recurrent test results and the MQTG validation test results of the initial evaluation. Investigation of any discrepancy between the MQTG and recurrent FFS/FTD performance is left to the discretion of the FSTD operator and the competent authority. For devices where CT&M is used for the initial evaluation, the test results for the recurrent evaluation should be acceptable if they are within the tolerances to the MQTG test results as given in [AMC1 FSTD(H).300(b)(3)](#_DxCrossRefBm1778671996). (3) Differences between the two sets of results, other than minor variations attributable to repeatability issues (see Appendix 1 of this AMC) that cannot easily be explained, may require investigation. (4) The FSTD should still retain the capability to over-plot both automatic and manual validation test results with reference data. (5) For FNPT special consideration for recurrent qualification is provided in [AMC5 FSTD(H).300](#_DxCrossRefBm1778672003) paragraph (e)(4).
