B767-300 FLT CREW HAS STALL WARNING AND HDG DEV DURING BOACH 2 DEP LAS.

Narrative

DEPARTING LAS ON BOACH 2 DEP; IT WAS A HOT DAY WITH A HVY AIRPLANE. ON TKOF; WE WERE CLRED FOR TKOF AND TO MAINTAIN VISUAL SEPARATION FROM AN AIRBUS ROLLING JUST AHEAD OF US. AS WE TOOK OFF; I NOTICED THAT THE R ENG WAS AT 590 DEGS (40-50 DEGS C HOTTER THAN THE L ENG) BUT WITHIN LIMITS. ALSO DURING THE CLB; THE TCAS FAILED; MAKING IT MORE DIFFICULT TO MAINTAIN VISUAL SEPARATION FROM THE AIRBUS. AS WE CLBED AND RAISED THE FLAPS TO THE FLAPS 1 DEG POS; THE STALL WARNING CAME INTO VIEW ON THE ADI AND OUR AIRSPD DECREASED INTO THE STALL WARNING AREA. OUR VERT SPD DECREASED FROM +2000 FPM TO +800-900 FPM. I MAINTAINED WINGS LEVEL AND DECREASED PITCH TO GET THE AIRPLANE TO ACCELERATE. AS THE ACFT ACCELERATED OUT OF THE STALL WARNING AREA; I ASKED THE FO FOR A TURN TO THE BOACH DEP. AT THIS TIME ATC CALLED AND ASKED US TO TURN TO A HDG OF 180 DEGS (THEN LATER DIRECT HEC). HE ALSO ASKED US WHAT HAPPENED. I TOLD HIM THAT WE HAD A HVY AIRPLANE. HE STATED; 'IT WOULD BE NICE IF YOU TELL SOMEBODY.' I FELT THAT IT WAS IMPORTANT TO KEEP THE ACFT FROM STALLING AND DELAY THE TURN. IT FELT AS THOUGH WE ENTERED A DOWNDRAFT AS WE WERE CLBING. THERE WAS NO TFC OR TERRAIN CONFLICT. THE BOACH 2 DEP IS MARGINAL FOR HVY ACFT ON A HOT DAY.
