There is NO necessary relationship between visual approaches and the incidence of unstable approaches.
It may not be necessary, and I don’t disagree with that, but facts are facts. The FOQA data presented from the airline concerned was unambiguous and presented in a large international forum with over one hundred airlines present.
You can have all the opinions on your old airline that you like, but when facts like this are permeated through the industry it makes the argument of letting pilots handfly and do visual approaches that much harder.
IMHO until there are some more hull losses from complete incompetence/magenta lining the airlines’ desire to avoid unstable approaches (or level busts like the recent A320 vis app into YMML) will sadly rule and manual flight will be actively discouraged.
