A flight simulator was a partial model of a aircraft or spacecraft, used to train pilots.

As of 2153, Trip Tucker had built flight simulators before and felt creating a craft to trick Degra would be no different. (ENT: "Stratagem")

Starfleet Academy had flight simulators. When Cristóbal Rios time travelled from 2401 to 2024, he told a local in vague terms about sneaking into a simulator as an 8-year-old child. He said that alarms went off when he broke the highest score for any cadet in history. (PIC: "Assimilation")
