##### AMC1 ORA.FSTD.105(a)(3) Maintaining the FSTD qualification *ED Decision 2026/006/R* **QUALIFICATION TEST GUIDE (QTG) PERIODIC TESTING – FUNCTIONS AND SUBJECTIVE TESTS** (a) To conduct the functions and subjective tests of the FSTD over the 24-month cycle, the organisation operating the FSTD should: (1) initiate the 24-month cycle from the end of the month in which the initial qualification took place, unless another date is agreed with the competent authority; (2) develop and document a detailed testing plan that: (i) aligns with the MQTG functions and subjective tests and with FSTD equipment, specifications and capabilities, specified in the ESL; and (ii) specifies timelines and responsibilities; (3) determine which tests are applicable to each FSTD and perform these tests; (Note: further guidance on typical test profiles which are part of the functions and subjective tests is provided in [GM1 ARA.FSTD.100(a);(b);(c)](#_DxCrossRefBm2072462883)); (4) divide the functions and subjective tests described in the MQTG into a minimum of four approximately equal parts, ensuring that each part covers all the sections of the functions and subjective tests table in the applicable qualification basis; (5) conduct the tests progressively, ensuring that all tests are completed over the course of 24 months (e.g. a quarter of tests every six months) and that the areas to be tested in each fly-out are selected so that no area is left untested over the 24-month period; (6) conduct testing of an appropriate sample of malfunctions during the functions and subjective tests, to assess the impact of the malfunctions on affected features, systems, subsystems, components or parts; and (7) implement tools and/or methods to assess the FSTD’s performance and identify potential discrepancies during the functions and subjective testing. (b) In each subsequent conduct of functions and subjective testing, the organisation should include additional malfunctions which have not been included in the previous samples. (c) The organisation operating the FSTD should use aircraft flight manuals, pilot operating handbooks and checklists (normal, abnormal and emergency) that correspond to the FSTD to support the functions and subjective testing. These may be documents of the real aircraft. If the FSTD does not correspond to a real aircraft (e.g. the FSTD has generic fidelity level(s)), a manual/handbook should be created by the organisation operating the FSTD with details for operating procedures and description of the aircraft systems, including any limitations to support the training use. *[applicable from 30 April 2028 — ED Decision 2026/006/R]*
