'chimbu' that's true what you say to some degree but a lot of those young airman didn't make it, many crashed during landing & T/off. And those guys wouldn't have been worrying too much about stabilized App's either just get the damned thing on the ground any way you can!
I imagine that a lot of Airlines don't practice NPA's too much in the Sim these days & that coupled with rarely doing them anyway out there on the line with what's generally accepted as very inexperienced co-drivers beside them all add to high levels of risk.
It's all about risk, someone's done the numbers on risk here & came up with a 'scare-factor' number that means nope not letting them do anymore viz App's.
