CAE Inc. (formerly Canadian Aviation Electronics) is a Canadian manufacturer of simulation technologies, modelling technologies and training services to airlines, aircraft manufacturers, defense customers, and healthcare specialists. CAE was founded in 1947, and has manufacturing operations and training facilities in 35 countries. In 2017, the company's annual revenue was CAD $2.705 billion.

CAE sells flight simulators and training devices to airlines, aircraft manufacturers and training centres. It licenses its simulation software to various market segments and has a professional services division.

The simulators include basic training devices CAE 400XR and CAE 500XR, and full-motion products such as the CAE 3000, CAE 5000 and CAE 7000XR. These simulators are available for commercial use. In 2016, the company sold 53 Full-Flight Simulators.

In 2001, CAE Inc. acquired BAE Systems's Flight Simulation and Training division, formerly known as Reflectone Inc, a publicly listed company founded in 1939, and based in Tampa, Florida. Reflectone sold flight simulators to the military and provided pilot training on its premises.

CAE conducts airline pilot training and business jet pilot training in its 50 aviation training centres worldwide.

In the United States, the firm is a supplier of initial and recurrency training for airlines such as JetBlue and non-airline based companies, including charter and cargo operators. In December 2001 the firm acquired Simuflite training centers in Dallas, Texas and Morristown, New Jersey, which are now called CAE SimuFlite.

In 2011, CAE decided to leverage its experience in aviation and simulation-based training to enter a new emerging market: simulation-based medical education.

CAE purchased Medical Education Technologies Inc. (METI), a Sarasota-based company renowned notably for its innovative patient simulator, the HPS. This acquisition brought a direct sales force in the U.S., close customer relationships and a worldwide distributor network. Today, CAE's healthcare simulation solutions business unit is a global leader in medical simulation training technology to improve patient safety in clinical settings.

The CEO, Marc Parent, was named in this role in October 2009. He has more than 25 years of experience in the aerospace industry.
