Done it again boys - 2 threads with the same (or similar) title. Look - I'm a pilot with a desperately short attention span and a dislike of long words; I'm unlikely want to go hunting around to find out the difference between two "Navigators". Rant over.
On the subject of navs: The ones who know where they are(location, not seat)are the dogs b***ocks - at least there isn't a debate/fight about who's go it is to fly. It also saves the pilot the embarassment of having to admit that he has little idea what all the squiggles on the map mean - that's enough - back to the bar!
PS: it is a shame that it's no longer PC to incinerate them though.
