Narrative:

Prior to crossing trm on climb out we were vectored off course to a heading of 060 degrees for traffic. Then we were turned further left to an 030 degree heading and instructed passing FL310 fly direct blh. Then came another vector of 150 degrees direct blh. Then at 27 DME from blh, another vector heading 180 degree to blh. Crossing blh at FL330, we initiated a left 20 degree bank turn to intercept J-169 (082 degree outbnd). Next came another ATC vector to 030 degrees, then 020 degrees, 30 degree angle of bank was used. Lax center advised us to expedite turn to avoid R2306B. Lax asked what heading we were passing through (it was about 080-090 degrees) when they implied that we had violated the restr area. Next came a frequency change to abq center (132.45) and we were given yet another vector 090 degrees direct ewm when able. We were not allowed to fly the airway. ATC instructions were followed precisely. 160-180 degree heading changes for traffic are excessive. Airway intercept angles of 100 degrees or more close in to the station at FL330 with a full airplane is illogical. ATC cannot reasonably expect us to successfully circumnav special airspace if not allowed to fly filed jet routes as cleared.

Title: RADIUS OF 100 DEGREE TRACK CHANGE CARRIES ACR LGT INTO RESTRICTED AREA.

Narrative: PRIOR TO XING TRM ON CLBOUT WE WERE VECTORED OFF COURSE TO A HDG OF 060 DEGS FOR TFC. THEN WE WERE TURNED FURTHER L TO AN 030 DEG HDG AND INSTRUCTED PASSING FL310 FLY DIRECT BLH. THEN CAME ANOTHER VECTOR OF 150 DEGS DIRECT BLH. THEN AT 27 DME FROM BLH, ANOTHER VECTOR HDG 180 DEG TO BLH. XING BLH AT FL330, WE INITIATED A L 20 DEG BANK TURN TO INTERCEPT J-169 (082 DEG OUTBND). NEXT CAME ANOTHER ATC VECTOR TO 030 DEGS, THEN 020 DEGS, 30 DEG ANGLE OF BANK WAS USED. LAX CTR ADVISED US TO EXPEDITE TURN TO AVOID R2306B. LAX ASKED WHAT HDG WE WERE PASSING THROUGH (IT WAS ABOUT 080-090 DEGS) WHEN THEY IMPLIED THAT WE HAD VIOLATED THE RESTR AREA. NEXT CAME A FREQ CHANGE TO ABQ CTR (132.45) AND WE WERE GIVEN YET ANOTHER VECTOR 090 DEGS DIRECT EWM WHEN ABLE. WE WERE NOT ALLOWED TO FLY THE AIRWAY. ATC INSTRUCTIONS WERE FOLLOWED PRECISELY. 160-180 DEG HDG CHANGES FOR TFC ARE EXCESSIVE. AIRWAY INTERCEPT ANGLES OF 100 DEGS OR MORE CLOSE IN TO THE STATION AT FL330 WITH A FULL AIRPLANE IS ILLOGICAL. ATC CANNOT REASONABLY EXPECT US TO SUCCESSFULLY CIRCUMNAV SPECIAL AIRSPACE IF NOT ALLOWED TO FLY FILED JET ROUTES AS CLRED.
