Sometimes the initial missed approach alt is below your current alt so you have to carry on down
You don't have an instrument rating, do you ? Unless you are on the prescribed track, etc., you are not permitted to "carry on down". I do hope that your comment was tongue in cheek
Didn't read the original question properly!
We did some sim training, on ils with initial miss app alt 1500'
Given go around from tower about 1800'
This was to get us to understand how to get aircraft out of ils mode so it would level at 1500' to a defined dme on the plate, then continue the misap procedure.
We did know where we were though
