A320 CREW HAD A TRACK DEV WHEN THEY TURNED TOWARD AN INCORRECT HDG ON DEP AT LGB.

Narrative

LGB-OAK L SEAT DEP FROM RWY 30; CLRNC CALLED FOR 270 DEG HDG AFTER DEP ON RWY HDG OUT OF 1500 FT. AUTOPLT ON AT APPROX 200 FT. OUTSIDE SCAN WAS BEGUN FOR TFC. AT 1500 FT; HDG OF 180 DEGS WAS SELECTED AND VERBALLY CALLED OUT. FO NEVER CAUGHT INCORRECT HDG SINCE HE WAS PERFORMING A FREQ CHANGE AT THE SAME TIME. AS ACFT TURNED THROUGH A HDG OF ABOUT 240 DEGS; ATC ASKED FOR A HDG OF 280 DEGS AND BROUGHT THE INCORRECT TURN TO OUR ATTN. THE ACFT WAS BROUGHT IMMEDIATELY BACK TOWARD 270 DEG HDG. ACFT OVERSHOT TURN BY ABOUT 45 DEGS. THERE WERE NO TCASII WARNINGS OR TFC INCURSIONS. TOO MUCH ATTN WAS GIVEN IN THIS CASE TO LOOKING FOR TFC AND DISTR US FROM CATCHING THE INCORRECT HDG EARLIER. SOME DEPS REQUIRE A 180 DEG HDG AND OTHERS REQUIRE A 270 DEG HDG FROM THIS RWY; DEPENDING ON THE DIRECTION OF FLT. WE WERE ADVISED BY SOCAL APCH THAT THIS HAS BECOME A RECURRING PROB WITH OUR COMPANY DEPS. STANDARD DEPS SHOULD BE GIVEN OUT OF THIS ARPT; EVEN SIMPLE THINGS SUCH AS A DIFFERENCE IN HDG CAN BECOME MISSED WHEN LOOKING FOR TFC. ACR OPS OUT OF THE CLASS D THROUGH THE CLASS E AIRSPACE BELOW THE CLASS B AIRSPACE WITH A L TURN THROUGH AN AIRWAY; VFR CORRIDOR AND PRACTICE AREA ALL WHILE PERFORMING A FREQ CHANGE ARE DEMANDING; TO SAY THE LEAST. STANDARD DEPS WOULD BE HELPFUL.
