ALTDEV DURING GAR.

Narrative

WE WERE CLRED TO LAND SFO RWY 19L. WIND WAS 180 DEGS AT 18 KTS WITH GUSTS TO 33 KTS. CAPT WAS HAND FLYING ACFT. AT 100 FT AGL WE GOT WIND SHEAR. ACFT ROLLED TO THE L 30 DEGS BANK. CAPT WENT AROUND. TWR CLRED US TO 2000 FT MSL; THEN HANDED US OVER TO DEP. DEP CLRED US TO 3000 FT. OUT OF 2500 FT. CAPT ASKED FOR CTR AUTOPLT TO COMMAND. THE AUTOPLT DID NOT CAPTURE THE 3000 FT ALT SET IN THE MODE CTL PANEL WINDOW. THE ACFT WAS CLBING AT 2800 FPM AT THE TIME I ENGAGED THE AUTOPLT. I TOLD THE CAPT WE DID NOT CAPTURE OUR ALT. HE TURNED OFF THE AUTOPLT AND HAND FLEW ACFT DOWN TO 3000 FT MSL FROM 3500 FT MSL. ON THE GAR THERE WAS ANOTHER ACFT WHICH HAD JUST TAKEN OFF FROM RWY 19R. WE WERE BOTH MAKING L TURNS AT THE SAME TIME. I COULD KEEP VISUAL CONTACT FROM THE R SIDE AND THE CAPT COULD NOT. CAPT SAW THE ACFT BEFORE WE STARTED OUR TURN; AND KEPT OUR L TURN VERY TIGHT. I THINK THE REASON FOR THE ALTDEV WAS PLT OVERLOAD WITH THE WIND SHEAR; TRYING TO MAINTAIN VISUAL WITH ANOTHER ACFT ON THE SAME DEP. ALSO; FLYING IN AND OUT OF CLOUDS AND CHANGING RADIO FREQS AS WELL AS GETTING NEW INSTRUCTIONS FROM TWR AND DEP CTL.
