进近与着陆是飞行过程中最重要和最关键的阶段。近40年的统计表明,约30％-50％的喷气式运输机的空难事故发生在这一阶段,而其中涉及机组人为因素的事故高于65％。通常,人们将这最后的进近与着陆称为“最后2分钟”,“危险飞行期”。事实上,进近着陆是机动飞行较多的阶段,影响飞行的可变因素较多,尤其是在复杂的气象条件,终端航路要求及空管限制等因素的影响 Approach and landing are the most important and crucial phases in the flight. Nearly 40 years of statistics show that about 30% -50% of jet aircraft crash occurred at this stage, of which more than 65% involving crew-induced accidents. Normally, this final approach and landing is referred to as the “last 2 minutes”, “dangerous flight period.” In fact, approach landing is a period of more maneuvering flights and there are more variables that affect the flight, especially under complex meteorological conditions, terminal route requirements and air traffic control restrictions
