TRU Simulation + Training (TRU, usually pronounced as in "true") is an American manufacturer of flight simulators and training devices for civil and military markets.

It is a subsidiary of Textron and was formed in 2014 when previously acquired simulator manufacturers Mechtronix and OPNICUS were merged with part of Textron Systems division.

A further company, business jet training provider ProFlight, was acquired and merged later that year.

[1][2] In 2014, TRU was selected by Boeing for the development and supply of a 737 MAX full flight training suite, and two years later the company secured a 10-year agreement for a similar product for the newly developed 777X.

[2][3][4] In November 2020, the non-US based (Quebec based) civil aviation business (previously Mechtronix sites) was sold to CAE [5] after Textron announced shutting down this section of its TRU Simulation business in July of the same year.
