A pilot's experience has little to do with safety. For a start, the majority of prangs are with high houred, experienced pilots. So just for that reason, publishing this data would serve absolutely no purpose whatsoever. Furthermore, I don't trust the media (it's they who rely on that idiot Yates for "expert" opinion) nor the traveling public to use data in any meaningful way. A useful and worthwhile published list would be an independent score of a pilot's ability. It would also include the number of take-off and landings in the past 30 days, the amount of hand-flying vs automatic flight, the number of visual and non-precision approaches, the number of FDM exceedences etc. and so forth. But that data will never be released. There would be little long haul flying. The Queen would never fly (unless BA management massage the figures or let a "gash" line pilot fly her) and our friends at RYR would probably top the "ability" table.
