Narrative:

On departure climb out from north philadelphia, PA, airport, I turned approximately 180 degrees farther right than I should have. The clearance was to turn right after takeoff direct to the yardley VOR. I mentally mistook the tail of the RMI needle on the flight director to be the 'to' indication and proceeded to fly toward that direction. I recognized my error simultaneously with the controller. I had already begun the turn back to the correct heading when the controller ordered it also. There was a breakdown in cockpit communication, and I was the initiator of the breakdown. I had seen what I wanted to see on the EFIS HSI, not what was actually depicted. I ignored other indicators (RMI, to/from arrow, etc) that would have confirmed the correct heading to be flown after takeoff. Moral: keep the flow of information going in the cockpit--you never know when your partner may have his/her head up and locked!

Narrative: ON DEP CLBOUT FROM NORTH PHILADELPHIA, PA, ARPT, I TURNED APPROX 180 DEGS FARTHER RIGHT THAN I SHOULD HAVE. THE CLRNC WAS TO TURN RIGHT AFTER TKOF DIRECT TO THE YARDLEY VOR. I MENTALLY MISTOOK THE TAIL OF THE RMI NEEDLE ON THE FLT DIRECTOR TO BE THE 'TO' INDICATION AND PROCEEDED TO FLY TOWARD THAT DIRECTION. I RECOGNIZED MY ERROR SIMULTANEOUSLY WITH THE CTLR. I HAD ALREADY BEGUN THE TURN BACK TO THE CORRECT HDG WHEN THE CTLR ORDERED IT ALSO. THERE WAS A BREAKDOWN IN COCKPIT COM, AND I WAS THE INITIATOR OF THE BREAKDOWN. I HAD SEEN WHAT I WANTED TO SEE ON THE EFIS HSI, NOT WHAT WAS ACTUALLY DEPICTED. I IGNORED OTHER INDICATORS (RMI, TO/FROM ARROW, ETC) THAT WOULD HAVE CONFIRMED THE CORRECT HDG TO BE FLOWN AFTER TKOF. MORAL: KEEP THE FLOW OF INFO GOING IN THE COCKPIT--YOU NEVER KNOW WHEN YOUR PARTNER MAY HAVE HIS/HER HEAD UP AND LOCKED!
