Narrative:
During climb out, dallas 1 departure, captain left radios to attend other duties. I was flying, on autoplt, and was cleared for heading 095 degrees to intercept 072 degree radial from dfw VOR. I connected the inertial navigation system (INS) and flight management system (FMS) to complete the course transition. I failed to insure the navigation system accepted the changes. As I realized the radial overshoot, ZFW called to query my heading, clearance, and to request a turn to on course. Proper FMS and navigation system inputs were made and a course correction was made. I failed to properly verify all changes made to the FMS and navigation system, with the captain off frequency there was no back up for my mistake. I will insure all changes to the FMS and navigation system are properly verified and that the aircraft responds accordingly.

Title: A MD88 MAKES A TRACK ERROR CLBING OUT FROM DFW. FO IS PF AND MAKES IMPROPER INPUTS TO NAV COMPUTER. CAPT IS NOT AVAILABLE TO XCHK INPUTS INTO THE NAV SYS.
Narrative: DURING CLBOUT, DALLAS 1 DEP, CAPT LEFT RADIOS TO ATTEND OTHER DUTIES. I WAS FLYING, ON AUTOPLT, AND WAS CLRED FOR HDG 095 DEGS TO INTERCEPT 072 DEG RADIAL FROM DFW VOR. I CONNECTED THE INERTIAL NAV SYS (INS) AND FLT MGMNT SYS (FMS) TO COMPLETE THE COURSE TRANSITION. I FAILED TO INSURE THE NAV SYS ACCEPTED THE CHANGES. AS I REALIZED THE RADIAL OVERSHOOT, ZFW CALLED TO QUERY MY HEADING, CLRNC, AND TO REQUEST A TURN TO ON COURSE. PROPER FMS AND NAV SYS INPUTS WERE MADE AND A COURSE CORRECTION WAS MADE. I FAILED TO PROPERLY VERIFY ALL CHANGES MADE TO THE FMS AND NAV SYS, WITH THE CAPT OFF FREQ THERE WAS NO BACK UP FOR MY MISTAKE. I WILL INSURE ALL CHANGES TO THE FMS AND NAV SYS ARE PROPERLY VERIFIED AND THAT THE ACFT RESPONDS ACCORDINGLY.
