The current XJT line builder globalizes. The you undo ALL the global effects with trip trading. Even Eagle in BK didn't want a global solver and managed to avoid it. Republic avoided it as well. However, the XJT pilot group has to do something that everyone who's come before them avoided. While other groups ran away from global solver, they run right to one because they can preserve the 75 hour line for the ultra senior while the majority has to fly a bunch. What they fail to understand is that, they will get their 75 hour line but the solver still has to cover the days. Therefore, the 75 hour line wishers will work just as many days all while making guarantee.
