L3Harris Commercial Aviation Solutions (L3 CTS) is a flight training provider and manufacturer of civil flight simulators based in Crawley, England.

In 2012, when TTS was partially acquired, the company's name was changed to "L-3 Communications Link Simulation and Training UK Limited" (L-3 Link UK).

[5] L3 CTS and TTS are still co-located on the same site in Manor Royal, Crawley, and share the same ancestry, rooted in the US simulation business created by Ed Link in the 1930s and in the British simulator manufacturer Redifon (later Rediffusion).

[6] Recently, L3 Airline Academy has been granted the contract to train the RAF (Royal Air Forces) Multi Engine Aircraft pilots.

In November 2023, L3Harris Commercial Aviation Solutions was sold to TJC for $800 million.
