Well I do brief the step downs on the ILS, just for this very reason. I am not going to burn a couple $ in fuel to go around on an approach that I can finish. I guess if you aircraft requires a change in config, then well I guess, but I have never heard of that.
My whole thing is not having to go around unnecessarily and waste gas and ultimately your tax dollars. I think that silly.
If you go 1 dot below and you are still above LOC mins do you still go around? or you do you recapture the GS? cause if you never recapture you can still descend to the LOC mins and continue the approach. Again to facilitate not having to go around.
