JACDEC

The abbreviation JACDEC, or J.A.C.D.E.C. stands for Jet Airliner Crash Data Evaluation Centre. The authors Jan- Arwed Richter and Christian Wolf offer under this name to a flight safety ranking of airlines as a service.

History and offer

Headquartered in Hamburg JADEC was created in 1989 as a project of two students into life. The focus of their data collection and interpretation is the collection and preparation of accident information in the civil aviation sector. All total losses (English, hull losses ') and critical incidents in the worldwide flight operations are listed there. Among other things, they derive information from the flight safety of their built up since 1991 database.

JACDEC also provides background information for journalists and editors at the current research on issues of aviation safety. The author Jan- Arwed converter operates, among others, as a freelancer for the aviation magazine Aero International and provides text articles, images and illustrations of aircraft accidents for newspapers and publishing editors.

On the English-language website to airline rankings and accident statistics can be found on individual airlines, countries and aircraft types.

For a fee, you can get there even more in-depth security expertise on certain airlines.

Statistics

The JACDEC database serves as the basis for statistics on the frequency of losses at the different types of aircraft and airlines. A JACDEC - specific statistical measure is the JACDEC Safety Index, an index designed to enable the comparison of flight safety of airlines. The basic idea of the index is to put deaths and aircraft total losses to the kilometers flown by revenue generating passengers in relation. An airline with no fatal accidents and no aircraft total loss has an index value of 0.000 and 0.001.

This index was modified in 2010 and expanded to one decimal place. All accident data are now limited to the last 30 years of an airline. The previous time limit in 1973 accounted for. In addition, the membership of an airline in the global security program IOSA IATA joins with a safety assessment.

The safety index is to serve the passenger as evidence of the differences of the accident rate among the airlines exist. Therefore, the JACDEC Security Index includes only flights which is paying passengers have been found on board. Freight, training, testing, and ferry flights omitted. Also not considered accidents on the ground, where no passengers are on board.

JACDEC published the annual ranking of the 60 largest Safety airlines in the world in the aviation magazine Aero International.

Criticism

• The JACDEC index does not allow any conclusions about the current safety standard of an airline. Thus, for example, has the airline Adria Airways with 15.721 a very bad value, although they accident-free flying for over 30 years.
• The index is based on JACDEC no question of guilt in case of accidents. The statistical accident history no distinction according to the causes of accidents. Whether technical failure, human error, weather conditions or terrorism, all accidents are recorded as equal risk for the passenger.
• The selected JACDEC for the index calculation method entails that an airline that scrapped a badly damaged aircraft after a flight accident with no deaths as a total loss, a worse JACDEC Safety index obtained as if the damaged machine had been repaired and operated.
• If an airline taken over by another, as for example with Lauda Air and Austrian Airlines was the case, the accident rate of the acquired airline is completely eliminated. The crash of Lauda Air, therefore, has no effect on the index of Austrian Airlines.
• The JACDEC index takes no account of whether an airline mainly short - or long-haul flying. During a long-distance machine spends many hours each day in a safe statistically cruise, performs a short-range machine in the same period a number of take-offs and landings that pose a much higher risk of accidents.
• The JACDEC - index only flight performance and accidents of the past 30 years. All previous total losses and casualties of the airlines eliminated. Newly established companies automatically get a value of 0.00. This allows the JACDEC index a statement like "Lufthansa is infinitely more secure than Ghana International Airlines".
