The current system does work, but I still believe it would be a major improvement if the PNF's side stick was somehow linked to and moving in the same way as the PF's one. Nobody can deny that would be a welcome feature. Obviously this should not necessarily be a mechanical linkage. An electronic feedback, combined with today's "dual input" warning and priority button would be optimal in my opinion. There's little doubt in my mind that that's what the future will bring. No problems in case of incapacitation in this way either.
This is the sole aim of my University project. Summed it up nicely!
