Brilliant for what it was designed for, low vis approaches to cat1 or cat 2 minimas in aircraft with limited or no automatics as the landing pilot doesn’t have to try to acquire the runway visually whilst flying on instruments at the same time.
In aircraft types where low vis approaches are flown automatically probably not so necessary, although personally I think cat3a approaches where the captain takes over when visual but up until then the f/o has flown the approach and flys the go around if needed are better than the system where the captain does the whole thing and the f/o monitors. But that’s a personal opinion, and others will think differently.
