Just reading this info regarding the CTAF calls post 24th November.
I question the new procedures in one regard - there are no references to giving ETA calls when inbound.
Another aircraft, a King Air call sign FEN, broadcasts that it is inbound at 25NM to the west. A King Air flies at about four miles per minute and so the pilots of both the Cessna and the Piper can calculate that the King Air will be joining the circuit in about six or seven minutes.
I was always taught to give an ETA when giving my inbound call - now it appears I have to memorise the performance characteristics of every aircraft in the register and work out for myself when someone else is turning up? Or am I reading too much into this?
