Bear in mind that the default coding for a waypoint is fly-BY - conventional procedure fixes are, by definition, fly-OVER. The fifference could be critical under some circumstances.
Which circumstances did you have in mind?
That aside, my original question wasn't so much on construction of SIDs and TERPS. It's a question of where does it say what my CP says it says - that you can't do a pilot-nav SID with two FMCs, two IRSs, two GPSs, two autopilots, two pilots and a partridge and a pear tree?
We fly enroute with navaids out all the time. VOR U/S? No prob. Where does it say that
that is acceptable?
