Situation: Increasing the classroom training and emphasizing the communication skills can't compensate pilot's lack of actual flying time, thus can't reduce the possibility of pilot error. so the method should be rethinked. Reasoning: Since actual flying time is a more important factor than classroom training time and communication skills in solving the problem of pilot error, it must be assumed that lack of actual flying time have close relationship with pilot error. D fill the gap. C although point out a relationship between lack of actual flying time and plane crashed , but it not necessarily assumed, for the relationship is not so fixed which rule out other factors that may also affect the incidence of plane crashes. |
