    Evidence: "21.42 - Preferred hypotheses On the basis of the foregoing, the commission considered the following hypotheses as explanations for the pivotal event: 21.421 - Hypothesis No. 1: the abnormally high rate of descent was the result of an unintentional command on the part of the crew because they believed the vertical mode selected on the auto-pilot to be other than that which was actually selected."

    Evidence: "CHAPTER 2.2 - ANALYSIS OF FACTORS CONTRIBUTING DIRECTLY TO THE ACCIDENT [ p. 217] ... 22.336 - Conclusion In conclusion, the design of the rotary selector switch and the window displaying the vertical flight path control parameters means that the coherence between the selection of vertical mode and the selected value is critical. Also, the probability of confusion in this area seems to be considerable, particularly for a crew new to the aircraft. The spatial distribution between the mode selector switch and the value selector switch tends to accentuate the natural weakness in the human operator's cognitive process. " (page 230)
    Issue: interface may be poorly designed (Issue #39) See Issue details
    Strength: +3
