From what I have seen (and unless someone can definitively state otherwise):
- All planning will still be done on the sqns and not by DTMA/Gp - in fact, I'm not even sure that they can see the crewing bit of BOCS.
- I don't see why it shouldn't cope with a 3 week course as it's just another event and the computer won't care what the reason, just that you're unavailable for flying.
- The new crewing module qualifications bit seems work like a chinagraph board that automatically updates itself on the basis of the trips you do and gives you a 'traffic light' warning of approaching and exceeding currency. Frankly, it looked very impressive and can cope with anything from CCS to some esoteric BTR.
