Does anybody know, if the cockpit designers of our two main competitors (yes, the sidestick company and its yoke rival) or their avionics suppliers conducted an in-depth testing of their respective man-machine-interface?
This includes scientific sound eye and motion tracking under normal circumstances and simulated emergencies.
Furthermore: Is the max deflection of a sidestick clearly visible for the other crewmembers - taking into account their position in the cockpit (left / right seat or standing in the middle of the flight deck) and the illumination?
