The direction this thread has taken, like the many others on the same subject in the past is further justification of the failure of CASA to write the AIP in a clear and unmistakeable manner.
"Cleared to leave CTA" and "Cleared visual approach" are both readback requirements.
Sorry Buzz, but since 1997 neither have been a readback requirement, in fact the use of the work "cleared" in your examples is yet another interpretation in these discussion. Only with the recent amendment that requires the read back of approach clearances has visual approach been made a read back requirement.
Part of the problem is that many instructors and airline training pilots have made up their own interpretation on this subject and have taught it. There is nobody, repeat nobody either (either as a group or individual) in industry or within CASA that has ever applied any standardisation to eliminate those interpretations that are not what the intention of the AIP authors was in 1997. .... hence our present discussion.
Obviously these discussion are related to Oz procedures not our mates in NZ who follow ICAO but with their own interpretations!
