【正确答案】
B
【答案解析】综合推断题。由FAA determined that including pilots who fly cargo planes a large portion of the aviation industry would add too much to the cost of carrying out the changes．But the Independent Pilots Association has taken legal action asking the government to set one level of safety for all pilots．可知．美国联邦航空管理局决定货机的飞行员并不适用于该规定，但是Independent Pilots Association已经采取了法律手段要求政府为所有的飞行员设置同一水平的安全保障标准。也就是说Independent Pilots Association对新规定的适用人员感到不满意，他们认为新规定应适用于所有的人员。故选B。
