Narrative:

2 capts were assigned this flight, 2 day trip, 5 cities. We briefed the SID before engine start. Loupe 9 was 'in the box,' so PF was going to fly the commands while PNF backed up with raw data. Takeoff was non-eventful. SID requires runway heading to 1.8 DME of sjc then right turn heading 120 degrees within 4.0 NM of sjc VOR. We saw this as a tight turn and briefed a 200 KT speed to keep within the 4.0 NM limit. PF rolled into the turn at 1.8 DME (FMS wanted to 'lead' the turn at less than 1.8 NM) at 27 degree bank. He then increased to 30 degree bank but we could not stay within 4.0 NM of VOR. On heading 120 degrees we were 4.8 NM from VOR. Departure asked 'next time, please stay within the 4.0 DME.' next time we will try with flaps and 180 KTS to see if we can stay within the 4.0 NM limit. We will also roll directly to 30 degree bank. Contributing was wind out of the northwest which we did not consider in our briefing. Next time we will watch the wind direction. Other than these things, we are not sure what else we can do. This is a tight maneuver in our opinion. (I wonder how often aircraft drift out of the 4.0 NM limit.)

Title: THE FLC OF A CPR H25C OVERSHOOTS THEIR TURN DURING THE LOUPE 9 SID DEP PROC FROM SJC, CA.

Narrative: 2 CAPTS WERE ASSIGNED THIS FLT, 2 DAY TRIP, 5 CITIES. WE BRIEFED THE SID BEFORE ENG START. LOUPE 9 WAS 'IN THE BOX,' SO PF WAS GOING TO FLY THE COMMANDS WHILE PNF BACKED UP WITH RAW DATA. TKOF WAS NON-EVENTFUL. SID REQUIRES RWY HEADING TO 1.8 DME OF SJC THEN R TURN HEADING 120 DEGS WITHIN 4.0 NM OF SJC VOR. WE SAW THIS AS A TIGHT TURN AND BRIEFED A 200 KT SPD TO KEEP WITHIN THE 4.0 NM LIMIT. PF ROLLED INTO THE TURN AT 1.8 DME (FMS WANTED TO 'LEAD' THE TURN AT LESS THAN 1.8 NM) AT 27 DEG BANK. HE THEN INCREASED TO 30 DEG BANK BUT WE COULD NOT STAY WITHIN 4.0 NM OF VOR. ON HEADING 120 DEGS WE WERE 4.8 NM FROM VOR. DEP ASKED 'NEXT TIME, PLEASE STAY WITHIN THE 4.0 DME.' NEXT TIME WE WILL TRY WITH FLAPS AND 180 KTS TO SEE IF WE CAN STAY WITHIN THE 4.0 NM LIMIT. WE WILL ALSO ROLL DIRECTLY TO 30 DEG BANK. CONTRIBUTING WAS WIND OUT OF THE NW WHICH WE DID NOT CONSIDER IN OUR BRIEFING. NEXT TIME WE WILL WATCH THE WIND DIRECTION. OTHER THAN THESE THINGS, WE ARE NOT SURE WHAT ELSE WE CAN DO. THIS IS A TIGHT MANEUVER IN OUR OPINION. (I WONDER HOW OFTEN ACFT DRIFT OUT OF THE 4.0 NM LIMIT.)
