Narrative:

Operating in R2508. IRS/FMS navigation from N36 degrees 40.0 mins to W118 degrees 20.0 mins to N36 degrees 40.0 mins to W117 degrees 15.0 mins, mach .78, FL370, under positive control 'joshua' radar. At 117 degrees 15.0 mins west, I initiated a left turn, 25 degree bank, to reverse course. Approximately 1/4 through the 180 degree turn, 'joshua' called and said 'border, 3 (or 4) mi.' I disconnected the autoplt and steepened the turn to 45 degrees bank. We still departed the R2508 complex by 1 mi or less. No traffic involvement. A turn at that location should have given ample border clearance. Wind at 35000 ft was approximately 80-90 KTS from 270 degrees, which obviously contributed. Solution: move the turn point 3 mi west. I will initiate this at our location. A right turn also would have solved the problem due to the angle of the boundary line.

Title: A FACTORY TEST PLT, IN AN MLG, FLEW OUT OF THE EDWARDS TEST AREA NEAR J92.

Narrative: OPERATING IN R2508. IRS/FMS NAV FROM N36 DEGS 40.0 MINS TO W118 DEGS 20.0 MINS TO N36 DEGS 40.0 MINS TO W117 DEGS 15.0 MINS, MACH .78, FL370, UNDER POSITIVE CTL 'JOSHUA' RADAR. AT 117 DEGS 15.0 MINS W, I INITIATED A L TURN, 25 DEG BANK, TO REVERSE COURSE. APPROX 1/4 THROUGH THE 180 DEG TURN, 'JOSHUA' CALLED AND SAID 'BORDER, 3 (OR 4) MI.' I DISCONNECTED THE AUTOPLT AND STEEPENED THE TURN TO 45 DEGS BANK. WE STILL DEPARTED THE R2508 COMPLEX BY 1 MI OR LESS. NO TFC INVOLVEMENT. A TURN AT THAT LOCATION SHOULD HAVE GIVEN AMPLE BORDER CLRNC. WIND AT 35000 FT WAS APPROX 80-90 KTS FROM 270 DEGS, WHICH OBVIOUSLY CONTRIBUTED. SOLUTION: MOVE THE TURN POINT 3 MI W. I WILL INITIATE THIS AT OUR LOCATION. A R TURN ALSO WOULD HAVE SOLVED THE PROBLEM DUE TO THE ANGLE OF THE BOUNDARY LINE.
