The reference to adverse conditions, reporting standards etc are also not very convincing to me, if airlines like EI, VS, SK, and AY are rated a lot higher than BA in the rankings..
Respectfully I disagree. A flawed methodology doesn’t reflect trends even with changes in the order of the airlines.
As for safety culture of other airlines appearing higher, that is a significant problem with a ranking system, it is not accurately interpretable without knowing th me standard deviation of the scores, or an ability to determine the risk of type 1 and type 2 errors.
Effectively it is a completely unscientific method of both measuring and reporting the safety of airlines, that is implemented based on the ranking company’s commercial benefit alone amplified by cheap journalism.
