PCT CTLR EXPRESSED CONCERN REGARDING LACK OF CTLR BRIEFINGS/TRNG REF RNAV PROCS; I.E. FLY OVER VS. FLY BY RESTR.

Narrative

WONCE WAYPOINT ON TERPZ1 DEP PROC IS CHARTED AS A FLY-BY WAYPOINT. WONCE HAS A XING RESTR OF AT OR ABOVE 11000 FT. THE VAST MAJORITY OF ACFT FLY OVER WONCE XING IT AT OR ABOVE 11000 FT CLBING TO 17000 FT (17000 FT CLB IS ISSUED BY ATC). SOME ACFT FLY BY WONCE INSTEAD OF OVER IT. I QUESTIONED THE PLT WHY HE WASN'T FLYING OVER WONCE LIKE I EXPECTED AND HE STATED THAT IT WAS A FLY-BY WAYPOINT. AFTER RESEARCHING IT I FIND THAT THE PLT IS CORRECT; WONCE IS NOT CHARTED AS A FLY-OVER WAYPOINT. CTLRS BASE THEIR CTL INSTRUCTIONS ON THE EXPECTATION THAT ACFT WILL FLY THE TERPZ DEP PROC FLYING OVER EACH POINT CHARTED. I WAS NEVER TAUGHT THAT THE WAYPOINTS WERE FLY-BY AND NOT FLY-OVER. AT A MINIMUM; A TEMPORARY SOLUTION TO ENSURE THAT ACFT ARE NOT CLBED INTO ACFT FLYING THE TERPS DEP PROC IS TO ADVISE CTLRS THAT ALL WAYPOINTS ARE FLY-BY AND NOT FLY-OVER. A PERMANENT SOLUTION IS TO CHANGE THE WONCE WAYPOINT TO A FLY-OVER WAYPOINT SO THERE IS NO GUESSING WHETHER THE ACFT WILL FLY OVER OR FLY-BY WONCE AND INTO THE PATH OF ANOTHER ACFT.
