Narrative:

The problem arose during taxi, on the ground. There was a possible conflict with another parked aircraft. I was in a power back mode, relying on my signal man for directions. The power back required a straight back movement and then a large turn to avoid the concourse and parked aircraft behind. The aircraft was backed too far back before the turn was started. The signal man had to call for an abrupt stop to avoid backing into aircraft behind it. It was close to a conflict. Backing up an aircraft using reverse thrust involved a lot of coordination between the pilot and the signal man. If the aircraft's path back looks at all questionable, the power back should be stopped early and not allowed to develop into a possible emergency situation.

Title: ACR PIC CITES A PROB WITH GND CREW FLC COORD DURING A PWR BACK RAMP OP RAMP DEP PROC. POTENTIAL CONFLICT GND.

Narrative: THE PROB AROSE DURING TAXI, ON THE GND. THERE WAS A POSSIBLE CONFLICT WITH ANOTHER PARKED ACFT. I WAS IN A PWR BACK MODE, RELYING ON MY SIGNAL MAN FOR DIRECTIONS. THE PWR BACK REQUIRED A STRAIGHT BACK MOVEMENT AND THEN A LARGE TURN TO AVOID THE CONCOURSE AND PARKED ACFT BEHIND. THE ACFT WAS BACKED TOO FAR BACK BEFORE THE TURN WAS STARTED. THE SIGNAL MAN HAD TO CALL FOR AN ABRUPT STOP TO AVOID BACKING INTO ACFT BEHIND IT. IT WAS CLOSE TO A CONFLICT. BACKING UP AN ACFT USING REVERSE THRUST INVOLVED A LOT OF COORD BTWN THE PLT AND THE SIGNAL MAN. IF THE ACFT'S PATH BACK LOOKS AT ALL QUESTIONABLE, THE PWR BACK SHOULD BE STOPPED EARLY AND NOT ALLOWED TO DEVELOP INTO A POSSIBLE EMER SIT.
