Hi there,
as a current TATC i felt i ought to add my way of thinking!
I'm currently recoursing on area foundation at the college, and to me it has been vital. At the end of my previous foundation course, I was in no way ready to pass on to the next stage. Now, having had the benefit of extra time on the simulators (and observing the operational world whilst holding), i feel comfortable with taking the summatives (starting next fri

) and - provided i pass - moving on to the next stage.
In answer - No, recoursing is no bad thing (other than an extra 3months on TATC pay!)
Personally, I feel that my case that i needed probably a week or two longer to have been comfortable with the level of traffic - however there's no reason to believe that this is the general feeling!
