Narrative:

Departing lax runway 7R, imperial 2 departure. At about 1200 ft AGL, before slat retraction, I had a TA by 'RA' on the TCASII system commanding stop climb and descend. Indications on the TCASII scope showed conflicting aircraft less than 1 mi, 200 ft above to my left 9:30-10 O'clock location. Upon advising departure control I was informed an aircraft had taken off the north complex runway 6 on the gabre 4 departure had not made his left turn at the 4 DME to a heading of 055 degrees leading to the conflict. The TCASII worked as advertised. We did not see the other aircraft, do not know its type, company or how close we actually were. The question of when to make the left turn to 055 at 4 DME on the gabre 4 departure should be resolved. Do they always turn at 4 DME or wait for departure control or the tower to issue the turn? The new procedures on the lax 1 departure off 25R, the tower or departure will no longer issue the first left turn to 220 degrees. The pilot turns upon crossing a radial off the ventura VOR. Do not have the chart at home to identify that radial. Maybe the first turn should always be made by the pilot at a DME or radial. This will reduce the radio traffic by at least 2 transmissions.

Title: ON E TKOF FROM LAX AN ACR WDB GOT A TCASII RA AS THEY PASSED 1200 FT. ACFT OFF PARALLEL RWY HAD FAILED TO TURN IN ACCORDANCE WITH SID.

Narrative: DEPARTING LAX RWY 7R, IMPERIAL 2 DEP. AT ABOUT 1200 FT AGL, BEFORE SLAT RETRACTION, I HAD A TA BY 'RA' ON THE TCASII SYS COMMANDING STOP CLB AND DSND. INDICATIONS ON THE TCASII SCOPE SHOWED CONFLICTING ACFT LESS THAN 1 MI, 200 FT ABOVE TO MY L 9:30-10 O'CLOCK LOCATION. UPON ADVISING DEP CTL I WAS INFORMED AN ACFT HAD TAKEN OFF THE N COMPLEX RWY 6 ON THE GABRE 4 DEP HAD NOT MADE HIS L TURN AT THE 4 DME TO A HDG OF 055 DEGS LEADING TO THE CONFLICT. THE TCASII WORKED AS ADVERTISED. WE DID NOT SEE THE OTHER ACFT, DO NOT KNOW ITS TYPE, COMPANY OR HOW CLOSE WE ACTUALLY WERE. THE QUESTION OF WHEN TO MAKE THE L TURN TO 055 AT 4 DME ON THE GABRE 4 DEP SHOULD BE RESOLVED. DO THEY ALWAYS TURN AT 4 DME OR WAIT FOR DEP CTL OR THE TWR TO ISSUE THE TURN? THE NEW PROCS ON THE LAX 1 DEP OFF 25R, THE TWR OR DEP WILL NO LONGER ISSUE THE FIRST L TURN TO 220 DEGS. THE PLT TURNS UPON XING A RADIAL OFF THE VENTURA VOR. DO NOT HAVE THE CHART AT HOME TO IDENT THAT RADIAL. MAYBE THE FIRST TURN SHOULD ALWAYS BE MADE BY THE PLT AT A DME OR RADIAL. THIS WILL REDUCE THE RADIO TFC BY AT LEAST 2 TRANSMISSIONS.
