Thanks for the fast reply Dave. I did a quick experiment. I tried, and was able, to put different altitudes into the duplicate waypoints EG: ANTLR 27000 and ANTLR 33000. What is the upshot of doing this? Which waypoint altitude will PFE use?
You'll get different altitudes assigned by ATC.
If you would like to show me a before and after screen shot of the entire waypoint display I may understand what it is you're trying to achieve.
I should note though that although the waypoints are duplicated, PFE will only allow a SID or START to end/start on one of the duplicated waypoints.
Correct. You can't have a SID or STAR starting/ending from nowhere. They are virtual waypoints for internal use
