Education/training loans?

I attend a private university for mechanical engineering where the tuition rate is high, $3618 per cl, however I get a good grant from the school, so a full course load only ends up costing me around $4000 per semester which isn't too bad. I want to pursue career pilot training outside of this however. I looked into sallie mae and a few other loan programs. Will I be able to get a training loan such as sallie mae if I already am on federal and private loans for my undergrad degree? I'd like to do the flight training while I am still in undergraduate school. I'm scheduled to graduate in spring 2011.
