Bloomin' hell. The last couple of responses seem to indicte to me that the professional IFR pilots think that they have the absolute responsibility for the "see-and-avoid". No. This is a shared responsibility Now and with NAS. You IFR types can rest assured that I am also looking out which decreases any risk significantly. I pride myself on the fact that when I hear an IFR RPT inbound call; I can manouvre my aircraft away from yours, sight and pass you. Of course today I have to tell you all about that, but with NAS I can SAFELY manouver out of your way, sight and pass without having to make a call or even bother you with my whereabouts. This will leave you with less (not more) to do in the landing phase and also be able to concentrate on aircraft which you do need to concern yourselves with. Comment? s welcomed.
