I think radiotelephony is left to the student pilot to pick up along the way of most PPL courses.I certainly found the text book(Trevor Thom)not the best written I've come across in many years of having to have such books.
Several months ago I posted a question on the ATC forum about the differences between RIS and RAS,availability and so on,the answers to which cleared up a few foggy areas.The new radiotelephony practical exam is not easy due to the vagueness engendered by some books,etc..
What do you guys think of the possible effect of the new National PPL given the fewer hours that will be required for the ticket and the problems encountered now with JAR PPL pilots?
