Air transportation occurrence data

Dataset from January 1995

With a view to advancing transportation safety, the TSB is publishing data from its Aviation Safety Information System (ASIS) on reportable accidents and incidents (which together are called occurrences) for use by industry and the public. The TSB gathers the data in the course of its investigations and uses it to analyze safety deficiencies and identify risks in the Canadian transportation system.

Aircraft Flight Recorders

Large commercial aircraft (over 12 500 pounds) are required to be equipped with a flight data recorder (FDR) and a cockpit voice recorder (CVR). These recorders are frequently called the "black boxes".

The CVR records radio transmissions and the acoustic environment in the cockpit, notably internal communications between the pilots and sounds such as engine noises.
