Sullenberger's RT was far from standard, but it was brief and to the point and in a critical situation such as the one he was in, was highly appropriate.
I just got back from a long trip to the States and while I generally find the standard of RT not as bad as some people on this forum would have it, it can be very poor at times. I can think of at least 5 or 6 occasions on the sector home where clearances had to be repeated largely because of poor RT technique. A phenomenon which I am noticing more and more from US operators is the press the R/T switch and say nothing technique. Nobody seems to think before they start transmitting. As we are told that US R/T is non-standard because of the busy airspace, I wonder how much time is lost because of it?
I also heard someone pretty much arranging a date between a departure radar controller and the female pilot of a regional jet. Seriously?
