I have to admit that I can't remember ever doing an ACR 7 approach using the "step down" method (or "dive" and "drive" as my American colleagues used to call it). Whilst it is probably perfectly legal, we were discouraged from such methods about 30 years ago when the CAA encouraged us (in writing) to instead attempt to follow a 3-degree stabilised approach when carrying out a Non-Precision Approach.
I can remember my task master getting me to fly an NDB approach into LGW on my final line check in the DC-10 when I joined Laker after I left the RAF. I can imagine that the noise created during a "dive" and "drive" with a DC-10 would have wakened every tree-hugger in Sussex!
