Narrative:

Event: while introducing glider student to simulated tow rope break after being towed to 250 ft AGL, our glider passed over departure end of parallel paved runway 33 as we were doing steep descending 180 degree turns to do downwind landing on sod runway parallel to paved runway used by power aircraft. A C152 was climbing out, unexpectedly, over paved runway 33 well behind us. As we completed most of our turn I saw the C152 about 200 yards south of us as it began a turn to the northwest to stay clear of us. We completed our planned downwind landing. My concern is our unplanned crossing over the departure end of 3500 ft runway when we should have been well east of it. Contributing factors were: cessna pilot possibly did not hear our unicom announcement of simulated rope break or did not know that it meant an abrupt turn by the glider. The tow plane was angling more to the east on climb out. The tow pilot not knowing we were going to turn left or right 180 degrees at 250 ft. Trees to east of glider sod runway as mental barrier to r-hand 180. Corrective action on my part should have been a button hook turn to east before starting left 220 degree turn to west. Our glider crew could have signaled the cessna to wait briefly before takeoff.

Title: GLIDER INSTRUCTOR AT HWV ARPT WITH STUDENT ANNOUNCED ON UNICOM THAT HE WOULD BE DOING A 'SIMULATED TOW ROPE BREAK.' THE GLIDER PLT STARTED THE MANEUVER AT THE DEP END OF THE RWY AND CAME IN CLOSE PROX WITH A C152 THAT HAD DEPARTED ON A PARALLEL HARD SURFACE RWY.

Narrative: EVENT: WHILE INTRODUCING GLIDER STUDENT TO SIMULATED TOW ROPE BREAK AFTER BEING TOWED TO 250 FT AGL, OUR GLIDER PASSED OVER DEP END OF PARALLEL PAVED RWY 33 AS WE WERE DOING STEEP DSNDING 180 DEG TURNS TO DO DOWNWIND LNDG ON SOD RWY PARALLEL TO PAVED RWY USED BY PWR ACFT. A C152 WAS CLBING OUT, UNEXPECTEDLY, OVER PAVED RWY 33 WELL BEHIND US. AS WE COMPLETED MOST OF OUR TURN I SAW THE C152 ABOUT 200 YARDS S OF US AS IT BEGAN A TURN TO THE NW TO STAY CLR OF US. WE COMPLETED OUR PLANNED DOWNWIND LNDG. MY CONCERN IS OUR UNPLANNED XING OVER THE DEP END OF 3500 FT RWY WHEN WE SHOULD HAVE BEEN WELL E OF IT. CONTRIBUTING FACTORS WERE: CESSNA PLT POSSIBLY DID NOT HEAR OUR UNICOM ANNOUNCEMENT OF SIMULATED ROPE BREAK OR DID NOT KNOW THAT IT MEANT AN ABRUPT TURN BY THE GLIDER. THE TOW PLANE WAS ANGLING MORE TO THE E ON CLBOUT. THE TOW PLT NOT KNOWING WE WERE GOING TO TURN L OR R 180 DEGS AT 250 FT. TREES TO E OF GLIDER SOD RWY AS MENTAL BARRIER TO R-HAND 180. CORRECTIVE ACTION ON MY PART SHOULD HAVE BEEN A BUTTON HOOK TURN TO E BEFORE STARTING L 220 DEG TURN TO W. OUR GLIDER CREW COULD HAVE SIGNALED THE CESSNA TO WAIT BRIEFLY BEFORE TKOF.
