I asked today about the tactile knobs on the switches and how you could misidentify an actuator with a wheel knob and an actuator with a wedge flap knob.
I'm told that the design of the controls on the particular aeroplane is crap and it is very easy to select the wrong actuator. particular care needs to be taken to identify that the correct actuator is selected.
considering the details I was given clinton was a victim of poor cockpit design.
