A takeoff/go-around switch (TO/GA; /ˈtoʊɡə/) is a switch on the autothrottle of modern large aircraft, with two modes: takeoff (TO) and go-around (GA). The mode is dependent on the phase of flight; usually, on approach to land, the autopilot will be set to approach mode, therefore if the TO/GA switch is pressed it will activate the go-around mode of the autothrottle; conversely, when takeoff is set on the autopilot, the switch activates takeoff mode of the autothrottle. On Boeing aircraft TO/GA modes are selected by a separate switch near the throttle levers, but on Airbus aircraft it is activated by pushing the thrust levers fully forward to the TO/GA detent.
