Narrative:

We were supposed to be on the flipr 4 departure from lax but never got on it. Finally we were cleared direct sli VOR and climb to 17000'. At about 15000' climbing and turning, center (or departure) called out traffic at 11 O'clock and 15500' (commuter light transport Y). We passed through his altitude quickly and over top of him about 700'. It didn't look as though it was close enough to have caused a TCAS RA (we didn't have TCAS), but it looked as though it may have violated radar sep rules. It was not your usual climbing cross-over. I don't know if he was VFR or IFR. If we had shallowed our climb to accelerate, it may have been too close. For our part, we may have erred by not using 30 degrees of bank to turn direct sli VOR. We made a shallower turn like used at a higher altitude because we were relatively close to the VOR. This may have put us further east by 1-2 mi more than the controller expected. Then again, if we had used a steeper bank, we may have gotten too close. I don't know if the bank used was a factor or not. However, in the future I plan to use 30 degree bank in departure/arrival areas for large turns. Then if ATC gets busy and forgets us, we will have done what he expected us to do before he forgot us.

Title: ACR MLG DEP LAX EXPERIENCES AIRBORNE CONFLICT WITH COMMUTER ACFT.

Narrative: WE WERE SUPPOSED TO BE ON THE FLIPR 4 DEP FROM LAX BUT NEVER GOT ON IT. FINALLY WE WERE CLRED DIRECT SLI VOR AND CLB TO 17000'. AT ABOUT 15000' CLBING AND TURNING, CENTER (OR DEP) CALLED OUT TFC AT 11 O'CLOCK AND 15500' (COMMUTER LTT Y). WE PASSED THROUGH HIS ALT QUICKLY AND OVER TOP OF HIM ABOUT 700'. IT DIDN'T LOOK AS THOUGH IT WAS CLOSE ENOUGH TO HAVE CAUSED A TCAS RA (WE DIDN'T HAVE TCAS), BUT IT LOOKED AS THOUGH IT MAY HAVE VIOLATED RADAR SEP RULES. IT WAS NOT YOUR USUAL CLBING CROSS-OVER. I DON'T KNOW IF HE WAS VFR OR IFR. IF WE HAD SHALLOWED OUR CLB TO ACCELERATE, IT MAY HAVE BEEN TOO CLOSE. FOR OUR PART, WE MAY HAVE ERRED BY NOT USING 30 DEGS OF BANK TO TURN DIRECT SLI VOR. WE MADE A SHALLOWER TURN LIKE USED AT A HIGHER ALT BECAUSE WE WERE RELATIVELY CLOSE TO THE VOR. THIS MAY HAVE PUT US FURTHER E BY 1-2 MI MORE THAN THE CTLR EXPECTED. THEN AGAIN, IF WE HAD USED A STEEPER BANK, WE MAY HAVE GOTTEN TOO CLOSE. I DON'T KNOW IF THE BANK USED WAS A FACTOR OR NOT. HOWEVER, IN THE FUTURE I PLAN TO USE 30 DEG BANK IN DEP/ARR AREAS FOR LARGE TURNS. THEN IF ATC GETS BUSY AND FORGETS US, WE WILL HAVE DONE WHAT HE EXPECTED US TO DO BEFORE HE FORGOT US.
