2. What is an LCA? Line Check Airman
3. Does FedEx give points for different airplanes or are they treated the same? Don't know
Does heavy times count the same as CRJ900 time? Don't know
4. Does FedEx give points for international experience? Don't know
5. The application ask for manual lands, what is the sweet spot number? Don't know
Sorry I can't help you with definitive answers! I suspect that there are different point values for each of the items you are asking about and an assumption can be made that more/bigger/farther is better in most cases. Just make sure you don't get too much more/bigger/farther etc. !!

"You must stay in the sweet spot, otherwise you are untrainable to our exotic FedEx methods..."
Good luck to everyone - it's worth the effort!
