Narrative:

Clearance issued right turn heading 340 degrees on takeoff (runway 31). At 400 ft AGL (I was PF), turned aircraft right to 340 degrees. Once on the correct heading, departure issued, 'turn to 270 degrees.' no direction (left or right) was specified. The captain has prior experience in airspace and had flown in new york terminal area frequently. He knew the reason for the right turn was to avoid teb arrs over the hudson, and arrs to the runway 22 (left traffic), even though a right turn would take longer to get to a 270 degree heading. At about a 030 degree heading, departure specified ('left turn to 270 degrees'). Captain queried ATC after the correction about it being a possible problem and ATC said no problem at all. Our perception having flown in the area regularly was that it was common to turn the long way around the compass and we often did turn right from the runway.

Title: CL-65 DEP FROM LGA MAKES LONG TURN TO ASSIGNED HDG.

Narrative: CLRNC ISSUED R TURN HDG 340 DEGS ON TKOF (RWY 31). AT 400 FT AGL (I WAS PF), TURNED ACFT R TO 340 DEGS. ONCE ON THE CORRECT HDG, DEP ISSUED, 'TURN TO 270 DEGS.' NO DIRECTION (L OR R) WAS SPECIFIED. THE CAPT HAS PRIOR EXPERIENCE IN AIRSPACE AND HAD FLOWN IN NEW YORK TERMINAL AREA FREQUENTLY. HE KNEW THE REASON FOR THE R TURN WAS TO AVOID TEB ARRS OVER THE HUDSON, AND ARRS TO THE RWY 22 (L TFC), EVEN THOUGH A R TURN WOULD TAKE LONGER TO GET TO A 270 DEG HDG. AT ABOUT A 030 DEG HDG, DEP SPECIFIED ('L TURN TO 270 DEGS'). CAPT QUERIED ATC AFTER THE CORRECTION ABOUT IT BEING A POSSIBLE PROB AND ATC SAID NO PROB AT ALL. OUR PERCEPTION HAVING FLOWN IN THE AREA REGULARLY WAS THAT IT WAS COMMON TO TURN THE LONG WAY AROUND THE COMPASS AND WE OFTEN DID TURN R FROM THE RWY.
