Frappe,
I doubt it has much effect in your case as it is only an hour; it may show an interest in aviation but shouldn't have any effect on which group you are put in for flight screening. If you had a few hundred hours on a sim then maybe they would put you in the advanced group.
No doubt there is someone here who can give you the official line on it.
