A case in point is a recent departure I made from a surprisingly busy non-towered airport in Upstate New York. There were about six airplanes operating in the pattern, unusual for a Wednesday morning in winter. There was one airplane ahead of me on the taxiway, a Piper Warrior, that announced his intention to depart the area to the southwest. I also happened to be departing the area to the southwest, in a faster airplane no less. I knew that if I only announced my direction of flight, this poor pilot would be worrying the whole time about being run into from behind. So I announced my intention to depart the area to the southwest at 4,500 feet.
