We fly so many ILS's were I work...even if you are doing a "visual". About once every other month would fly a RNAV or LOC using profile in the A300/310 and have to almost refresh my procedures so the crew was sure of what was going to happen. I think the profile mode during approaches in the A300/A310 is an accident waiting to happen (and has happened) because it really is a poor attempt at a modern VNAV approach.
