Dear Mister Moderator. Why Did this thread end up here? When I posted it I was trying to get pilots like my self, but from the other side of the pond, to clear up a mystery that does have potential flight safety implications. If you pm me I might tell you what they are. I have been flying heavy jets to the USA for over 10 years now. I understand what I believe the answer to my qustion to be. I just wanted to hear from the horse's mouth. Not start a "Pi**ing contest on a "Wannabe's" forum. Thanks!
