Narrative

DEPARTED RWY 36L; BEIJING; CHINA. ASSIGNED SID 'D04.' PROC CALLS FOR MAKING A L 360 DEG TURN BEGINNING AND ENDING AT 'LG' TO A HARD ALT OF 1200M. 840000+ LB TKOF. FMC PROGRAMMED FOR THE SID AND DEPICTED THE 360 DEG CIRCLE AT 'LG.' UPON REACHING 'LG;' IT AND THE CIRCLE DISAPPEARED AS WE PASSED IT. I INITIATED THE L TURN VIA HEADING SELECT; BUT ONLY SLEWED BUG PART WAY AROUND TO ASSURE L TURN. SOMEWHERE IN TURN; DEP ADVISED 'CANCEL RESTRS' OR PERHAPS 'CANCEL ALT RESTRS.' CAPT (PF) BEGAN ACCELERATING AND CALLING FOR RETRACTING FLAPS FROM 20 DEGS. SOMEWHERE IN THERE I GOT BUSY WITH THE RETRACTION AND NAV AND DIDN'T CONTINUE TO MOVE THE HEADING BUG THE FINAL 90%. CALL WAS MADE FOR 'FLAPS UP.' WE WERE TURNING (I BELIEVE) BUT STARTING TO GET CONTRARY THE FLT DIRECTOR DUE TO HEADING BUG IMPROPERLY SET. CHKED AIRSPD (INDICATED); WAS SUFFICIENT; SELECTED FLAPS UP. ADVISED CAPT OF NEED FOR TIGHTER TURN TO GET TO 'LG.' WAS COGNIZANT OF BEING TIGHT ON IAS FOR THE INCREASE IN RATE OF TURN. HAD VERY BRIEF BUFFET (SECOND OR TWO) AND ONSET OF STICK SHAKER; I CALLED 'STALL' AND AIDED IN INITIATING RECOVERY. OVERSHOOT OCCURRED DURING ALL THIS. CORRECTING BACK TO SID TRACK AND 'DEP' CLRED US DIRECT TO A SUBSEQUENT FIX. REST OF OUR 'SHIFT' NORMAL (DOUBLE CREWED). NOTE: FIRST TIME FLYING OUT OF PEK FOR BOTH PLTS. CAPT IS IN 'FIRST 100 HRS' ON B747-400. NOT A GREAT COMBINATION FOR A FAR 121.445 SPECIAL ARPT. CONFUSION BEGAN WHEN 'LG' AND ITS 'CIRCLE' DISAPPEARED WHEN PASSED. DIDN'T EXPECT THIS SINCE IT WAS A SELECTED SID (DEP/ARR). THERE IS A 260 KT SPD LIMIT IN THE 'CIRCLE.' INCREASING WORKLOAD/CONFUSION (INCLUDING 'CANCEL RESTRS') GOT US OFF OUR ORIGINAL PLAN. SHOULD HAVE COMPLETED THE 360 DEGS BEFORE CLEAN UP. WILL SUBMIT RPT TO COMPANY RECOMMENDING TO PUT AN ADVISORY NOTE IN COMMERCIAL CHART INFO PAGE REGARDING 'DISAPPEARING CIRCLE' AND NEED TO MAINTAIN SOME DEG OF FLAPS UNTIL COMPLETING THE 360 DEGS AND RE-PASSING 'LG' (FOR SPD LIMIT) REGARDLESS OF DEP INPUTS.
