These accident rates are not safety ratings.
There are many factors that contribute to the safety rating of an airline including, but not limited to, accident history, maintenance and operational procedures, types of training programs, age of fleet and specific routes flown.
In addition there are different ways to analyze past accident data including using number of hours flown, passenger miles completed or number of trips made. The accident rates below are based on only three basic parameters. Number of flights, the number of fatal accidents and the fatality rate of those accidents. The methodology is listed below the tables.
Aviation accidents are extremely rare, with the probability of a passenger being killed on a single flight at approximately eight million-to-one. If a passenger boarded a flight at random, once a day, everyday, it would statistically be over 21,000 years before he or she would be killed. |
