Airport; Human Factors; Procedure
[I was] performing Line Check from jumpseat. During initial taxi out from ORD gate; Captain made a left turn out and did not observe an RJ approaching from left on Taxiway A. I observed the aircraft approaching at high speed; and called for Captain to stop. The Captain; now seeing the conflict made an abrupt stop. The crew then reaffirmed their taxi clearance as ATC had not mentioned any traffic to follow on initial clearance. Crew continued taxi out and confirmed that Flight Attendant's and passengers were okay. Later in the flight the Purser claimed that she may have experienced an injury and would be filing a report. The rest of flight was uneventful.
Ground Control was very busy when we got our clearance to taxi. We were not given any traffic to follow on the nearby Taxiway A. I proceeded to add power as I was turning towards our assigned route to Runway 22L. I was making sure we were not going to come too close to an aircraft parked to my right. My LCA in the jumpseat saw a fast moving RJ on the taxiway behind us in my blind spot. He called for me to stop immediately which I did. Our speed was about 2 to 3 KTS; but the sudden stop caused our Lead Flight Attendant to fall against an open galley door. We asked her if she was OK and she said she was fine. She also said there was no problem to continue. The closest we got to the RJ was about 50 to 75 FT. We never crossed the taxiway edge line. The RJ never slowed down or took any action.
B757 flight crew was cleared to taxi from their pushed back position to Runway 22L via Taxiway A. As the aircraft began to move the Check Airman on the jump seat sights a fast moving RJ from the left rear and commands a stop.
