Beachdog2001,

That's true, it most likely would crash. What I would do in that situation is just not change it in the FMC. Just lookup the new ILS info in the charts. Granted this is not ideal, but we don't have much of a choice unless CS fixes the problem.

At least we've sort of narrowed down where the problem is. It really shouldn't be that tough to go in and squash this bug.
