Narrative:

ATC directed go-around on short final. Inside the final approach fix; the tower controller instructed an aircraft to 'line up and wait;' adding that an aircraft will cross down field. After the aircraft accepted the clearance to line up and wait; tower issued instructions for another aircraft to cross the runway at taxiway north. The aircraft that was crossing the runway took his time; delaying the takeoff clearance to the point that spacing became an issue. It was my observation that the aircraft on the takeoff roll might lift off; allowing us to continue the approach to a landing. The go-around was initiated prior to 120 ft; however; that was the lowest RA observed after the application of toga thrust. Tower issued a climbing left turn to 4;000 ft; heading 270 degrees. My concern during the latter portion of the approach was that a go-around initiated on our part would create a conflict with the aircraft on takeoff roll; (overtaking) and/or a possible conflict with a go-around or takeoff on the parallel runways. In my opinion it was safer to continue the approach than to initiate a go-around on our own. As a result; the go-around was initiated after tower issued the go-around instructions. As our aircraft passed over the numbers on the go-around; the aircraft on the runway rotated. Inexperienced tower controller who attempted to 'keep the operation moving' complicated by slower than normal taxi speed of aircraft crossing the runway.

Title: A321 Captain reports being issued a go around on very short final due to the departing aircraft not being airborne. The reporter had determined that a go around would be necessary but elected to wait for the ATC instructions due to possible conflict with the departing traffic ahead and off parallel runways.

Narrative: ATC directed go-around on short final. Inside the final approach fix; the Tower Controller instructed an aircraft to 'line up and wait;' adding that an aircraft will cross down field. After the aircraft accepted the clearance to line up and wait; Tower issued instructions for another aircraft to cross the runway at Taxiway N. The aircraft that was crossing the runway took his time; delaying the takeoff clearance to the point that spacing became an issue. It was my observation that the aircraft on the takeoff roll might lift off; allowing us to continue the approach to a landing. The go-around was initiated prior to 120 FT; however; that was the lowest RA observed after the application of TOGA thrust. Tower issued a climbing left turn to 4;000 FT; heading 270 degrees. My concern during the latter portion of the approach was that a go-around initiated on our part would create a conflict with the aircraft on takeoff roll; (overtaking) and/or a possible conflict with a go-around or takeoff on the parallel runways.
