Hi Judy
The issue of only having one approach plate during the approach is as far as I have seen very common in the Corporate environment, and as I see it,there is nothing wrong with that as long as a good SOP ensures that the crew are all in the loop for what is going on, and is going to happen. A good brief for the approach by the HP followed by a challenge of agreement/understanding accepted by the NHP. Whereafter the NHP crosscheckes the progress and aids the HP in adhering to the Briefed procedure, Good CRM will ensure that the crew both stay in the "loop".
Anyways, my 5 cents worth.
Good luck
