OzExpat. Thank you for your comments. That is exactly my worry. However it is difficult to penalise someone for using a legal document that is different from mine. I would have thought that all the Australian information that Jeppesen publishes comes from ASA. So why is it not identical? Does Jeppesen know something that ASA does not?
I was hoping that some Airline Pilots might enlighten me as to how they do their pre approach brief and verify the validity of the charts. There seems to be the attitude I've done the amendments, therefore they are correct. Perhaps I'm the only one making mistakes but lots of times when I do my amendments I find something different.
