Re: Hey software, get the fuck out of the way!
Whenever the two side stick receive a command, there is a very loud DUAL INPUT aural and visual warning on the FMA.
The end result of the command to the plane is the sum of the vectors of both inputs (so a full “pitch down” input would effectively nullify a “full pitch up input”).
Moreover, there is a SidestIck Priority button which, when pressed, disables the other one, gives a loud PRIORITY LEFT/RIGHT aural warning and a visual warning on the console of the pilot who lost priority. This is in case a stick fails and starts sending weird inputs.
