Narrative:
Shortly after takeoff we lost the entire 'a' hydraulic system, one of 2 main systems on the aircraft. (There is also a smaller limited 'standby' system). After consulting with our maintenance control and our onboard manuals we elected to continue to our destination of msp. In compliance with our emergency procedures, we began to prepare the aircraft for a single operating hydraulic system approach as we neared msp. One of the items we had to accomplish was the lowering of the flaps with an alternate electrical motor (instead of hydraulic). On final approach the motor for the outboard flaps failed, leaving us with just the inboard flaps. At this point we had to accomplish a new separate procedure for the failure of this system which necessitated going into a holding pattern, and burning extra fuel. In retrospect, I feel it may have been better to return to rno after the first failure of the hydraulic system. After any major system' degradation the possibility always exists for a second problem to arise. When this occurs with a minimum fuel state, your options for dealing with a second emergency may suddenly become very limited.

Title: SO DISAGREES WITH HIS CAPT OVER AN ABNORMAL PROC.
Narrative: SHORTLY AFTER TKOF WE LOST THE ENTIRE 'A' HYD SYS, ONE OF 2 MAIN SYSTEMS ON THE ACFT. (THERE IS ALSO A SMALLER LIMITED 'STANDBY' SYS). AFTER CONSULTING WITH OUR MAINT CTL AND OUR ONBOARD MANUALS WE ELECTED TO CONTINUE TO OUR DEST OF MSP. IN COMPLIANCE WITH OUR EMER PROCS, WE BEGAN TO PREPARE THE ACFT FOR A SINGLE OPERATING HYD SYS APCH AS WE NEARED MSP. ONE OF THE ITEMS WE HAD TO ACCOMPLISH WAS THE LOWERING OF THE FLAPS WITH AN ALTERNATE ELECTRICAL MOTOR (INSTEAD OF HYD). ON FINAL APCH THE MOTOR FOR THE OUTBOARD FLAPS FAILED, LEAVING US WITH JUST THE INBOARD FLAPS. AT THIS POINT WE HAD TO ACCOMPLISH A NEW SEPARATE PROC FOR THE FAILURE OF THIS SYS WHICH NECESSITATED GOING INTO A HOLDING PATTERN, AND BURNING EXTRA FUEL. IN RETROSPECT, I FEEL IT MAY HAVE BEEN BETTER TO RETURN TO RNO AFTER THE FIRST FAILURE OF THE HYD SYS. AFTER ANY MAJOR SYS' DEGRADATION THE POSSIBILITY ALWAYS EXISTS FOR A SECOND PROB TO ARISE. WHEN THIS OCCURS WITH A MINIMUM FUEL STATE, YOUR OPTIONS FOR DEALING WITH A SECOND EMER MAY SUDDENLY BECOME VERY LIMITED.
