近年,世界民航飞行事故发生率已趋向稳定,维持在每10万飞行小时失事0.1次(每10万次起降失事0.15次)左右。但是,随着民航飞行业务量的增长,如各国民航不采取措施减少空难发生率,专家预计:21世纪初,世界民航每周将发生一次大空难。这是人们不愿看到的,也是各国民航当局正在设法避免的事。加强安全管理,进行安全评估和监督,已成为当务之急。 1992年,美国政府公布了民用航空安全评估政策,要求美国联邦航空局对有飞往美国业务的航空公司注册国的民航管理状况进行安全评估,并按结果将其分成三类,采取维持飞入、改进后飞入、禁止飞入三种不同处置。此后,美国联邦航空局据此对飞入美国的航空公司进行安全评估,并由于对非洲个别国家的航空公
In recent years, the incidence of civil aviation flight accidents in the world has been steadily stabilizing, maintaining a rate of 0.1 for every 100,000 flying hours (about 0.15 for taking off and landing every 100,000 trips). However, with the growth of civil aviation flights, if civil aviation in each country does not take any measures to reduce the incidence of air strikes, experts predict that at the beginning of the 21st century, civil aviation in the world will have a major air crash every week. This is what people do not want to see, but also what civil aviation authorities of all countries are trying to avoid. Strengthening safety management, conducting safety assessment and supervision has become a top priority. In 1992, the U.S. government announced a civil aviation safety assessment policy requiring the FAA to conduct a safety assessment of the state of civil aviation administration in the countries where the airliners flying to the United States are operating and, according to the results, to classify them into three categories, , Improved after the flight, banned flying into three different disposal. Since then, the Federal Aviation Administration has carried out safety assessments of airlines flying into the United States and, as a result of air travel to individual countries in Africa,
