Narrative:

Departed vny runway 16R, turned to 260 degrees and leveled off at 2500' MSL, to remain below the arsa (bur). Approximately 1-2 mi west of the arsa (ca 7 mi southwest of vny) turned to 280 degrees magnetic heading and resumed normal climb (85 KIAS in an small aircraft). The student pilot was at the controls. In the vicinity of the bur runway 8 localizer, the student observed an medium large transport at our 10-11 O'clock and initiated a left turn to avoid the traffic. After the student initiated the turn, I saw the medium large transport and steepened the left bank to speed the sep. It did come close, but its hard to say what the sep was. The student and I were both clearing at the time, yet we didn't see the medium large transport because of our pitch attitude. The sun was also in our 10-11 O'clock position, and I'm sure this contributed to this occurrence. It was also hazy and looking westbound into the sun the visibility was certainly below the 7 mi reported by vny tower. The only things that may have been done to prevent this occurrence are, 1) run with all lights on in the terminal area, 2) s-turns while climbing, 3) lowering the nose periodically in the climb. I have since modified my climb profile to the practice area (12-15 mi west of vny) by staying underneath the localizer traffic in the 4000-5000' range, restricting my climb to a maximum of 3000' until north of the localizer.

Title: REPORTER AND TRAINEE TOOK EVASIVE ACTION IN CLIMB TO AVOID MLG.

Narrative: DEPARTED VNY RWY 16R, TURNED TO 260 DEGS AND LEVELED OFF AT 2500' MSL, TO REMAIN BELOW THE ARSA (BUR). APPROX 1-2 MI W OF THE ARSA (CA 7 MI SW OF VNY) TURNED TO 280 DEGS MAGNETIC HDG AND RESUMED NORMAL CLB (85 KIAS IN AN SMA). THE STUDENT PLT WAS AT THE CTLS. IN THE VICINITY OF THE BUR RWY 8 LOC, THE STUDENT OBSERVED AN MLG AT OUR 10-11 O'CLOCK AND INITIATED A LEFT TURN TO AVOID THE TFC. AFTER THE STUDENT INITIATED THE TURN, I SAW THE MLG AND STEEPENED THE LEFT BANK TO SPD THE SEP. IT DID COME CLOSE, BUT ITS HARD TO SAY WHAT THE SEP WAS. THE STUDENT AND I WERE BOTH CLRING AT THE TIME, YET WE DIDN'T SEE THE MLG BECAUSE OF OUR PITCH ATTITUDE. THE SUN WAS ALSO IN OUR 10-11 O'CLOCK POS, AND I'M SURE THIS CONTRIBUTED TO THIS OCCURRENCE. IT WAS ALSO HAZY AND LOOKING WBND INTO THE SUN THE VISIBILITY WAS CERTAINLY BELOW THE 7 MI RPTED BY VNY TWR. THE ONLY THINGS THAT MAY HAVE BEEN DONE TO PREVENT THIS OCCURRENCE ARE, 1) RUN WITH ALL LIGHTS ON IN THE TERMINAL AREA, 2) S-TURNS WHILE CLBING, 3) LOWERING THE NOSE PERIODICALLY IN THE CLB. I HAVE SINCE MODIFIED MY CLB PROFILE TO THE PRACTICE AREA (12-15 MI W OF VNY) BY STAYING UNDERNEATH THE LOC TFC IN THE 4000-5000' RANGE, RESTRICTING MY CLB TO A MAX OF 3000' UNTIL N OF THE LOC.
