Narrative:

We were on the hancock 5 arrival descending to FL200 between hnk and ign. The arrival was programmed and l-nav was captured. We were then given a vector of approximately 140 degree to intercept the ign 225 degree right to lendy intersection. L-nav was disarmed by 'heading select' for the 140 degree vector. The FMS was then reprogrammed with the ign 225 right to lendy and executed. L-nav was rearmed and the pfd annunciations were normal. I then proceeded with other programming and communications for the approach. We were almost on the ign 225 right when I noticed that we were not getting a capture. I immediately disconnected the autoplt and turned, but could not prevent the overshoot. Ny approach noticed right away and began giving us vectors and requested that we tighten the turn. I turned as tightly as I could. The rest of the arrival, approach and landing were flown west/O incident. ATC was very nice about it, but I felt it prudent to submit this report.

Title: TRACK DEVIATION. ACV TECH WDB ACFT.

Narrative: WE WERE ON THE HANCOCK 5 ARR DSNDING TO FL200 BTWN HNK AND IGN. THE ARR WAS PROGRAMMED AND L-NAV WAS CAPTURED. WE WERE THEN GIVEN A VECTOR OF APPROX 140 DEG TO INTERCEPT THE IGN 225 DEG R TO LENDY INTXN. L-NAV WAS DISARMED BY 'HDG SELECT' FOR THE 140 DEG VECTOR. THE FMS WAS THEN REPROGRAMMED WITH THE IGN 225 R TO LENDY AND EXECUTED. L-NAV WAS REARMED AND THE PFD ANNUNCIATIONS WERE NORMAL. I THEN PROCEEDED WITH OTHER PROGRAMMING AND COMS FOR THE APCH. WE WERE ALMOST ON THE IGN 225 R WHEN I NOTICED THAT WE WERE NOT GETTING A CAPTURE. I IMMEDIATELY DISCONNECTED THE AUTOPLT AND TURNED, BUT COULD NOT PREVENT THE OVERSHOOT. NY APCH NOTICED RIGHT AWAY AND BEGAN GIVING US VECTORS AND REQUESTED THAT WE TIGHTEN THE TURN. I TURNED AS TIGHTLY AS I COULD. THE REST OF THE ARR, APCH AND LNDG WERE FLOWN W/O INCIDENT. ATC WAS VERY NICE ABOUT IT, BUT I FELT IT PRUDENT TO SUBMIT THIS RPT.
