One thing I don't accept is you posting a "Quote" from me that YOU have altered. I specifically wrote ANO as that was quoted NOT the AIP to distinguish it from the CAA pub called the AIP. You need to understand the difference.
Yet again you have failed to read the post I keep referring to, which was about map printing accuracy not chinagraph lines drawn on it.
If you are using a GPS system with a current database, you can get much closer (should you so wish) to CAS boundaries with reasonable certainty that you will remain clear. Using a printed map and visual navigation introduces much more in the way of possible errors
Which one of those do you think the CAA will agree with?
