This is the first in a series of short articles on developments in flight simulation training devices for military, human-in-the-cockpit, rotary- and fixed wing aircraft. These articles will include “deep dives,” highlighting innovations in the devices themselves and in their underpinning technology foundations. Additionally, the series will identify the collaborative industry teams and acquisition program dynamics enabling the delivery of new FSTDs. The training devices in these articles will be randomly selected from military training enterprises around the globe.
