====== Benchmark testing by NASA ======
JSBSim was used by NASA in 2015 with other space industry simulation code, both to establish a ruler to judge future code for the requirements and standards of the space industry, as well as check agreement. The verification tested both atmospheric and orbital flight in [[Six degrees of freedom|6-degrees-of-freedom]] for simulations like JSBSim<ref>{{Cite web|date=January 2015|title=Check-Cases for Verification of 6-Degree-of-Freedom Flight Vehicle Simulations - Volume II|url=https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20150001264.pdf|url-status=live|archive-url=https://web.archive.org/web/20170227123110/https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20150001264.pdf|archive-date=2017-02-27|access-date=|website=NASA Technical Reports Server|at=See Section B.6.7 JSBSim|last1=Murri|first1=Daniel G.|last2=Jackson|first2=E.

However, the assessment found agreement for all test cases between the majority of participants, with the differences being explainable and reducible for the rest, and with the orbital tests agreeing "quite well" for all participants.<ref name=":62" /><ref name=":732"/>
