My airline every couple of months based on FOQA data shows us computer animated cockpit pictures and animations on our company app on our IPads of unstablized approaches that took place system wide last few months (obviously de identified and no flight numbers) so we can learn from what caused it. And no obviously the crew to whom this happened did not get in trouble for it.
Also based on this data we create our training events yearly. Now, if there is gross misconduct crews will get asked what happened to identify if there is a weakness in the training system, and where necessary pulled off line for extra training.
