FLC OF AN LGT ACR ACFT DECLARED AN EMER AND RETURN LAND DUE TO ACFT HYD PROB SHORTLY AFTER TKOF.

Narrative

SHORTLY AFTER DEP AFTER THE GEAR AND FLAPS WERE UP; THE SO NOTICED THE #1 A SYS HYD PUMP LOW PRESSURE LIGHT ON AND THE A SYS QUANTITY AT 0. WE DECLARED AN EMER AND REQUESTED VECTORS FROM MIA DEP WHILE WE ACCOMPLISHED OUR CHKLIST ITEMS AND MADE NOTIFICATION TO OUR COMPANY. THE GEAR HAD TO BE MANUALLY LOWERED AND THE FLAPS LOWERED BY THE ALTERNATE SYS. WE LANDED UNEVENTFULLY AND WERE TOWED TO THE GATE. THE FO FLEW THE ACFT WHILE I COORDINATED ALL ACTIONS INFLT. THIS WORKED WELL AND IS HOW WE TRAIN AT OUR COMPANY. I DO BRIEF ALL MY FO'S PRIOR TO TRIPS THAT; DURING AN EMER; THE FO WILL DO THE FLYING AND TALKING TO ATC AND USE OF THE AUTOPLT IS SUGGESTED. DURING THE INITIAL PART OF THE EMER; I REMEMBERED TO SET THE AUTOPLT ELEVATOR SERVO TO THE B SYS AND NOTIFYING THE FO OF THAT SO HE COULD USE THE AUTOPLT; BUT HE DID NOT USE IT DURING THE FLT WHILE BEING VECTORED AROUND. I SHOULD HAVE INSISTED THAT HE USE IT AS HE SEEMED A LITTLE OVERLOADED WHILE TRYING TO HAND FLY AND TALK TO ATC AT THE SAME TIME. THIS; IN TURN; DISTRACTED ME SLIGHTLY AS I TENDED TO WATCH HIM MORE THAN MIGHT HAVE BEEN NECESSARY HAD HE USED THE AUTOPLT.
