UAS is taught as a guided exercise/demo in type rating. Since it is not part of regulatory tick boxes of OPC/refresher it is not practiced again. This is not my idea. I stated the reality. There are more than 100 posts about. should, would. could have been done. You can't add more to that. To learn something from a disaster we need to take in the reality and that is they didn't know what happened and when they knew they didn't know how to deal with it. Then comes why and how. SFO and 447 are not same. One is about degraded ability to scan and the other is about lack knowledge to deal with a specific abnormality.
