The flight controller (also known as conn, conn officer, or astrogation plotter) was the crewmember on a Federation starship assigned the duty of piloting the vessel. This position combined the roles of the navigator and helmsman used previously. The term "conn" is also used to refer to the flight control station itself. (Star Trek: The Next Generation)
In 2371, the USS Voyager lost its astrogation plotter when the ship was brought to the Delta Quadrant by the Caretaker. A replacement was required when the ship began its course back to the Alpha Quadrant. (VOY: "Parallax")
