Narrative:

During takeoff roll a helicopter was observed descending and converging from left to right towards our intended flight path. Our rotation was done slower than normal and an immediate right turn was initiated after lift off to avoid the apparent converging path of the helicopter. Our aircraft passed within approximately 150' to the right of the helicopter. No traffic advisories were issued by the tower. The helicopter appeared to be operating a lot closer to the runway than normal.

Title: CLOSE PROX ACR-MLG HELICOPTER MANEUVERING NEAR THE TKOF RWY.

Narrative: DURING TKOF ROLL A HELI WAS OBSERVED DSNDING AND CONVERGING FROM LEFT TO RIGHT TOWARDS OUR INTENDED FLT PATH. OUR ROTATION WAS DONE SLOWER THAN NORMAL AND AN IMMEDIATE RIGHT TURN WAS INITIATED AFTER LIFT OFF TO AVOID THE APPARENT CONVERGING PATH OF THE HELI. OUR ACFT PASSED WITHIN APPROX 150' TO THE RIGHT OF THE HELI. NO TFC ADVISORIES WERE ISSUED BY THE TWR. THE HELI APPEARED TO BE OPERATING A LOT CLOSER TO THE RWY THAN NORMAL.
