Narrative:
The waypoints on this RNAV departure are runway specific and can only be loaded into the FMC in their entirety on the ground. We were assigned runway 18L for departure which would have us turning to the north on the west side of dfw. Before takeoff; we were assigned a 160 degree heading. After departure we were assigned a 100 degree heading followed by a clearance to corts intersection and the remainder of the departure. Corts is on the departure for runways 17R/C which loops around the east side of dfw; and this is a bad time to be heads down trying to load all the waypoints individually. By the time I had inserted corts into the FMC; executed; and turned the aircraft; the controller grew impatient and assigned a 010 degree heading. We were later cleared direct akuna. I told the controller the fixes were for the other runway and that we departed runway 18L. The controllers need to understand the implications of what they did with that clearance and how it affects crews along with the limitations of FMC's.
Original NASA ASRS Text
Title: B737-300 FLT CREW IS ISSUED A NEW RNAV DEP AFTER TKOF FROM DFW.
Narrative: THE WAYPOINTS ON THIS RNAV DEP ARE RWY SPECIFIC AND CAN ONLY BE LOADED INTO THE FMC IN THEIR ENTIRETY ON THE GND. WE WERE ASSIGNED RWY 18L FOR DEP WHICH WOULD HAVE US TURNING TO THE N ON THE W SIDE OF DFW. BEFORE TKOF; WE WERE ASSIGNED A 160 DEG HDG. AFTER DEP WE WERE ASSIGNED A 100 DEG HDG FOLLOWED BY A CLRNC TO CORTS INTXN AND THE REMAINDER OF THE DEP. CORTS IS ON THE DEP FOR RWYS 17R/C WHICH LOOPS AROUND THE E SIDE OF DFW; AND THIS IS A BAD TIME TO BE HEADS DOWN TRYING TO LOAD ALL THE WAYPOINTS INDIVIDUALLY. BY THE TIME I HAD INSERTED CORTS INTO THE FMC; EXECUTED; AND TURNED THE ACFT; THE CTLR GREW IMPATIENT AND ASSIGNED A 010 DEG HDG. WE WERE LATER CLRED DIRECT AKUNA. I TOLD THE CTLR THE FIXES WERE FOR THE OTHER RWY AND THAT WE DEPARTED RWY 18L. THE CTLRS NEED TO UNDERSTAND THE IMPLICATIONS OF WHAT THEY DID WITH THAT CLRNC AND HOW IT AFFECTS CREWS ALONG WITH THE LIMITATIONS OF FMC'S.
