AN AIRCRAFT X AND AN AIRCRAFT Y ON THE RAMP AT ATL WERE CLOSE TO CRITICAL GND CONFLICT TRYING TO MANEUVER AROUND A AIRCRAFT Z WITH A BROKEN TOW BAR.

Narrative

TAXIING ON THE RAMP IN ATL; I CAME UPON A DISABLED AIRCRAFT Z (TOW BAR BROKEN WHILE UNDER TOW) AT THE END OF THE RAMP AND AN AIRCRAFT Y ON THE ACTIVE TXWY TRYING TO ENTER THE RAMP. FROM MY VANTAGE POINT; IT APPEARED THAT I COULD TRANSITION BTWN THE ACFT; CLRING UP THE RAMP CONGESTION. HOWEVER; WHEN I TAXIED CLOSER; IT BECAME APPARENT I COULD NOT FIT. AS I WAS STOPPING; THE CREW REQUESTED THAT WE STOP. I SPECULATE THAT THE APPARENT ACFT MOVEMENT MADE THEM NERVOUS. WE WAITED UNTIL THE AIRCRAFT Z CONTINUED; THEN CLRED THE RAMP WITHOUT INCIDENT. THE AIRCRAFT Z DID NOT HAVE NAV LIGHTS ON. AIRCRAFT Y AGAIN MOVED AFTER DECISION WAS MADE TO TRANSITION. ALSO; A DESIRE ON MY PART TO CORRECT A SIT THAT WAS RAPIDLY BECOMING A LAG JAM WHICH WAS APPARENT UPON TAXIING CLOSER AND CHANGING THE ANGLE OF VIEW. I SHOULD HAVE WAITED UNTIL AIRCRAFT Z REPLACED THE TOW BAR. THE DECISION TO ATTEMPT TO EXPEDITE THE SIT WAS NOT MADE OUT OF HASTE. I WAS TRYING TO CONTRIBUTE TO THE SOLUTION; NOT THE PROB. STOPPING AND WAITING FOR THE AIRCRAFT Z TO MOVE WAS THE BEST ACTION TO TAKE.
