The critical flight stages D–I of the Air France 447 accident (in reference to fig. 3) as displayed in a Primary Flight Display design concept that provides additional affordance for direct interaction—a visual cue for pushing the nose down.

... was needed in the AF 447 scenario was a clear representation of the airplane's nose up attitude that would make the pilot point the nose down in order to compensate the misalignment, an indication that would, at first glance, lead to pushing the sidestick forward to push the nose down. Figure 5 illustrates a direct interaction approach to the display of the stall condition and compensation alignment for the Primary Flight Display as affordance that prompt pilots to naturally engage in downward velocity. The five PFD display stages for key events correspond to call-outs D-I in the timeline/vertical representation of the flight path in Figure 3 and are compared with the display of these five flight stages in the current PFD in Figure 4. ...
