Narrative:

At hou, the crew were assigned runway 12R for departure with a clearance up to 5000 ft. Upon taking the runway, the crew received a clearance of what they believed to be 'after departure, fly heading 290 degrees, cleared for takeoff runway 12R.' after takeoff and clear of obstacles, the crew began a right turn to 290 degrees. While passing through approximately 4000 ft MSL and 220 degrees, the tower advised it should have been a left turn, and now continue turn to 340 degrees and contact departure. The crew advised they believed it was a correct response and complied with ATC by turning to 340 degrees and calling departure. The turn was not only logical, but complied with standard procedures, since the right turn was 30 degrees closer than a left turn. The departure was under VFR conditions and no conflict with other traffic was observed visually or on TCASII. To avoid further conflict with ATC, the crew will question heading commands from ATC for preferred direction of turn.

Title: A C560 FLT CREW HAVE A MISUNDERSTANDING WITH ATC AS TO WHAT DIRECTION THE ACFT WAS SUPPOSED TO TURN AFTER DEP.

Narrative: AT HOU, THE CREW WERE ASSIGNED RWY 12R FOR DEP WITH A CLRNC UP TO 5000 FT. UPON TAKING THE RWY, THE CREW RECEIVED A CLRNC OF WHAT THEY BELIEVED TO BE 'AFTER DEP, FLY HDG 290 DEGS, CLRED FOR TKOF RWY 12R.' AFTER TKOF AND CLR OF OBSTACLES, THE CREW BEGAN A R TURN TO 290 DEGS. WHILE PASSING THROUGH APPROX 4000 FT MSL AND 220 DEGS, THE TWR ADVISED IT SHOULD HAVE BEEN A L TURN, AND NOW CONTINUE TURN TO 340 DEGS AND CONTACT DEP. THE CREW ADVISED THEY BELIEVED IT WAS A CORRECT RESPONSE AND COMPLIED WITH ATC BY TURNING TO 340 DEGS AND CALLING DEP. THE TURN WAS NOT ONLY LOGICAL, BUT COMPLIED WITH STANDARD PROCS, SINCE THE R TURN WAS 30 DEGS CLOSER THAN A L TURN. THE DEP WAS UNDER VFR CONDITIONS AND NO CONFLICT WITH OTHER TFC WAS OBSERVED VISUALLY OR ON TCASII. TO AVOID FURTHER CONFLICT WITH ATC, THE CREW WILL QUESTION HDG COMMANDS FROM ATC FOR PREFERRED DIRECTION OF TURN.
