Wasn't the Airbus with joystick on the left hand side of the pilot's seat, rather than yokes centrally located in front of both pilot seats, end up being a contributing factor to the loss of AF447, in that the co-pilot couldn't see what position the pilot had the control stick in?
- kpil 10y agoI think that more importantly they are not coupled, so that the input on one does not show or is felt on the other. It's possible to make simultaneous conflicting inputs and not notice. From a UX perspective, I think one major factor was that the pilot probably not noticed or forgot that stall protection was disabled due to the sensor faults. In normal law (mode) the pilot pulls back fully to get maximum lift - even near stall. Instead of a stick shaker warning, the aircraft just silently calculates a (reduced) elevator output. In my opinion this is a design flaw even if it's a convenient feature in normal flight, as a confused or stressed out pilot might follow the normal procedure in a bad situation - which will lead to a stall. As happened at least twice.
