Narrative:

During climb out, through 11000 ft, the so noticed 'a' hydraulic system quantity decreasing below 2.5 gallons. We followed the flight manual procedures while continuing to climb towards vxv. We did this in order to burn fuel, so as to avoid dumping, while giving us time to coordinate with air carrier operations. Air carrier operations concurred with our decision to land overweight and we began to proceed back to atlanta. We informed ZTL as well as our dispatcher that we requested emergency vehicles for our landing as well as a tug to tow us off the runway. We completed the descent, approach and before landing checklists per the procedures and landed on runway 27R in atlanta. Our landing weight was 160000 pounds with a speed at touchdown of 150 KTS. The sink rate at touchdown, as noted by the so, was 400 FPM. We stopped on the centerline of the runway and coordinated with maintenance through the headset to start the APU and shut down all engines. We were then towed to the gate. We made entries in the logbook for the 'a' hydraulic loss and the overweight landing.

Title: B727-200 CREW HAD 'A' SYS HYD FAILURE IN ATL CLASS B AIRSPACE.

Narrative: DURING CLBOUT, THROUGH 11000 FT, THE SO NOTICED 'A' HYD SYS QUANTITY DECREASING BELOW 2.5 GALLONS. WE FOLLOWED THE FLT MANUAL PROCS WHILE CONTINUING TO CLB TOWARDS VXV. WE DID THIS IN ORDER TO BURN FUEL, SO AS TO AVOID DUMPING, WHILE GIVING US TIME TO COORDINATE WITH ACR OPS. ACR OPS CONCURRED WITH OUR DECISION TO LAND OVERWT AND WE BEGAN TO PROCEED BACK TO ATLANTA. WE INFORMED ZTL AS WELL AS OUR DISPATCHER THAT WE REQUESTED EMER VEHICLES FOR OUR LNDG AS WELL AS A TUG TO TOW US OFF THE RWY. WE COMPLETED THE DSCNT, APCH AND BEFORE LNDG CHKLISTS PER THE PROCS AND LANDED ON RWY 27R IN ATLANTA. OUR LNDG WT WAS 160000 LBS WITH A SPD AT TOUCHDOWN OF 150 KTS. THE SINK RATE AT TOUCHDOWN, AS NOTED BY THE SO, WAS 400 FPM. WE STOPPED ON THE CTRLINE OF THE RWY AND COORDINATED WITH MAINT THROUGH THE HEADSET TO START THE APU AND SHUT DOWN ALL ENGS. WE WERE THEN TOWED TO THE GATE. WE MADE ENTRIES IN THE LOGBOOK FOR THE 'A' HYD LOSS AND THE OVERWT LNDG.
