over a long stretch of water, it is a necessity. if you have been over the bay of bengal, you would appreciate it even more.
but over europe, i thought it was a bit of a luxury until somebody told me otherwise. ok point taken.
i would like to share this incident that happened to a mate of mine.
he was given a re-route over the pacific and when loaded into his fms, the last portion of it was corrupted, resulting in a very nasty letter in the box when he got back. at the end of it all, we were told to print it all out and then load into the fms. so there's my contribution to this.
other than that, better than sliced bread i would say.
