We do the briefings then put the IPads on the side panels, we have got charging facilities on both sides of the cockpit, we get amendments coming in at fairly regular intervals, haven't really paid much attention as to how often they arrive, very simple and pretty quick to do the updates....considering the sorry state of our Internet.
Yup, real happy with the system...we can use the Bad Elf for track following, but with two FMS's and a separate GPS can't be bothered.
