Frequently
Asked Questions:
Why was Airline
Safety Records Created?
Airline-Safety-Records.com
was created to act as a safety "report card" on
America's airline industry. Airline accidents
unfortunately occur often enough that it is difficult to
determine which airlines are doing a better job at safety than
others. When accidents do occur, it's impossible to know
if one airline has more accidents because it is more careless
than others or because it simply flies more than others.
The statistics on this page adjust for the differences in the
number of trips an airline flies each year to produce a
standardized set of numbers that allow you to objectively assess
the safety record of all airlines.
Why are the
statistics reported in a number "per million
takeoffs"?
Since some airlines fly much
more often than others, a raw count of accidents, incidents, and
near mid-air collisions would not give an accurate picture of
how safe one airline is compared to another. Therefore all
statistics are reported as a number per 1,000,000 takeoffs.
For example, if an airline flew 5,000,000 takeoffs during the
year and had 10 accidents it would be reported as having 2
accidents per 1,000,000 takeoffs. Again, if another
airline flew only 500,000 takeoffs during the same year and had
the same number of accidents (10 accidents) they would be
reported as having 20 accidents per 1,000,000 takeoffs.
Clearly the second airline is less safe than the first (even
though they both had the same number of accidents during the
year).
Why are there no
statistics reported for foreign owned airlines?
In order to maintain a
standardized set of statistics that allow a fair comparison
among airlines, the source data has to be standardized.
Most foreign countries do not make their airline safety
information available. Those that do will have different
definitions for "accidents" or
"incidents". These different definitions and
methods make it impossible to objectively compare safety records
between US airlines and foreign airlines.
Why are some US
airlines not in the tables?
In order to be most effective,
the statistics on this site are reported for major airlines and
large national airlines. Smaller regional airlines are not
included. In addition, among the major and national
airlines, there must be an unbroken string of data available for
a period of five years in order to be included. This is
necessary to provide for a standardized comparison among all
airlines covered. Therefore airlines that have not been in
business for at least five years will not be found in these
tables.
