Moleslayer, I'm sure you are correct but I was'nt trying to be pedantic. I am trying to highlight the fact that on hearing PanPan, most pilots tend to shut up as they are immediately aware of a problem developing. Just chatting away to the controller about the odd little problem tends to get lost in the audiences background chitter chatter. I have found PanPan gets everyones ears up and the odd octave on the controllers voice! Clear, concise and to the point. Isn't that what R/T is meant to be about?
