I can't seem to work out how to do this. For example I have BRI, CI27, F127 then runway in FMC. I can delete BRI and add BRI90/10 and that appears as BRI02 no problem but if I Try to add another waypoint before that e.g BRI45/15  I get invalid waypoint. Also anywaypoint based on C127 e.g C12709/10 fails.  What is the right way to do this step by step.  I am trying to build a set of waypoints for a circuit all based on BRI.   I could do with an advanced FMC tutorial e.g when do you use ERASE and when DELETE etc.  Is this all explained in the manual -  even so a few examples would be great.

P/B/D must appear AFTER the waypoint they are using IIRC, as it uses it as as reference point.

 

This may or may not work (UNTESTED):

 

Enter BRI

AFTER it enter BRI90/10

AFTER THAT enter BRI45/15.

 

DELETE BRI when finished.

The topmost waypoint is the active waypoint.  You cannot change this.  You would just add that waypoint after BRI and then line select it to the top.  You could then add BRI back in after it, and the waypoints that follow as necessary.

 

For what it's worth, though, the whole point of circuit training is to get a hands-on sense of how the plane flies, so adding all of that into the FMC defeats the point.

PBD should always work.  There are many times you's use PBD without ever even using the root facility.

It works now. I had the syntax for the waypoint I was adding slightly wrong.
