MD80 FLT CREW HAS A EGPWS TERRAIN WARNING DURING DEP FROM ABQ.

Narrative

DURING INITIAL CLBOUT AT ABQ; AND IN A L TURN TO 310 DEGS I ASKED CAPT IF HE WANTED A VFR CLB. HE RESPONDED YES; AND WHILE ABEAM SANDIA PEAK BEGAN AN IMMEDIATE R TURN TO 060 DEGS. I SAW THAT WE WOULD CLR THE TERRAIN; BUT TOLD HIM THAT THIS IS NOT A GOOD IDEA; AND IMMEDIATELY BECAME CONCERNED ONLY IF SOMETHING WERE TO GO WRONG AT THAT POINT; EITHER AN ENG COUGHING OR SOMETHING TO DRAW OUR ATTN AWAY FROM FLYING THE ACFT. A MOMENT PASSED WHILE DECIDING WHAT TO DO; BASED ON CAPT'S EXPERIENCE LEVEL; AND IT WAS TOO LATE. WITH THE SLATS STILL EXTENDED; WE RECEIVED A TERRAIN ALERT FROM THE GPWS. I NOTICED HE INCREASED THE RATE OF CLB SLIGHTLY; AND THE ALERT SUBSIDED. SUPPLEMENTAL INFO FROM ACN 703017: DEP SAID WE COULD TURN HDG 060 DEGS WHEN ABLE. I TURNED TOWARD A GAP THAT EXISTS IN THE MOUNTAINS AND DID NOT RECEIVE THE TURNING PERFORMANCE I EXPECTED. FO SUGGESTED I NOT TURN. I DID ANYWAY. AS I ROLLED OUT AND CONTINUED TO CLB; A CAUTION TERRAIN WARNING OCCURRED. I INCREASED MY RATE OF CLB SLIGHTLY AND THE WARNING STOPPED. SHOULD HAVE WAITED TO TURN E UNTIL HIGHER.
