You need to keep up with the thread LB and not be so selective. Scroll down a bit further and you will see that I wrote this:
Round dials, low cloud very few options, I did my time in GA so I know what it is like however the RAlt was the one bit of equipment that I think could have been used to better effect than to work out where the water was. The cloud base was OVC 002 at the time of arrival. 200' is a CAT 1 minima so for a small jet continuing to 100' on a 3degree slope (which the approach chart states) will give you a good chance of seeing the runway. As I said before I don't think that ditching was the only option.
One can tell from your CASA legal background with this comment :
What’s a few hundred feet here or there during an IFR approach?
that you have never had to make that call. Must be very comfortable being a private pilot on a government salary. In this instance it was the difference between making a successful landing and ditching it into the ocean.
