Editing Flight simulator (section)

===Procedure===
Before September 2018,<ref>{{Cite web|url=https://www.faa.gov/documentlibrary/media/advisory_circular/ac_61-136b.pdf|title=FAA AC 61-136B}}</ref> when a manufacturer wished to have an ATD model approved, a document that contains the specifications for the model line and that proves compliance with the appropriate regulations is submitted to the FAA.  Once this document, called a Qualification Approval Guide (QAG), has been approved, all future devices conforming to the QAG are automatically approved and individual evaluation is neither required nor available.<ref>{{Cite web|url=https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_61-136A.pdf|title=FAA AC 61-136A}}</ref>

The actual procedure accepted by all CAAs (Civil Aviation Authorities) around the world is to propose 30 days prior qualification date (40 days for CAAC) a MQTG document (Master Qualification Test Guide), which is proper to a unique simulator device and will live along the device itself, containing objective, and functional and subjective tests to demonstrate the representativeness of the simulator compare to the airplane. The results will be compared to Flight Test Data provided by aircraft OEMs or from test campaign ordered by simulator OEMs or also can be compared by POM (Proof Of Match) data provided by aircraft OEMs development simulators. Some of the QTGs will be rerun during the year to prove during continuous qualification that the simulator is still in the tolerances approved by the CAA.<ref>{{Cite web|url=https://www.faa.gov/about/initiatives/nsp/media/14cfr60_searchable_version.pdf|title=FAA CFR Part 60}}</ref><ref name="CS-FSTD(A)">{{Cite web|url=https://www.easa.europa.eu/sites/default/files/dfu/CS-FSTD%28A%29%20%E2%80%94%20Issue%202.pdf|title=EASA CS-FSTD(A) Issue 2}}</ref><ref>{{cite web|url=http://www.caac.gov.cn/XXGK/XXGK/MHGZ/201511/P020151103350036735706.pdf |title=CAAC CCAR-60}}</ref>
