Narrative:

First officer and I noted traffic at our 11 O'clock position, opp direction, same altitude. As I began a turn north (right) away from V1, we called north.Y. TRACON and asked them about the aircraft. The controller replied that the aircraft, light transport Y, was a pop-up target, tracking 300 KTS over the ground. The controller recommended we turn left and descend. If we had followed his recommendations, we would have turned right into the jet and probably collided. At this point, a nervous supervisor came on the frequency and reported that the pop-up target had now descended rapidly out of radar coverage. TRACON failed to warn us of turbojet traffic, on a steady course, heading right at us, then suggested we turn so as to collide with same aircraft. I think controllers should receive more training in spatial relationships.

Original NASA ASRS Text

Title: CLOSE PROX COMMUTER LTT AND SECOND LTT OPPOSITE DIRECTION ON V1.

Narrative: F/O AND I NOTED TFC AT OUR 11 O'CLOCK POS, OPP DIRECTION, SAME ALT. AS I BEGAN A TURN N (RIGHT) AWAY FROM V1, WE CALLED N.Y. TRACON AND ASKED THEM ABOUT THE ACFT. THE CTLR REPLIED THAT THE ACFT, LTT Y, WAS A POP-UP TARGET, TRACKING 300 KTS OVER THE GND. THE CTLR RECOMMENDED WE TURN LEFT AND DSND. IF WE HAD FOLLOWED HIS RECOMMENDATIONS, WE WOULD HAVE TURNED RIGHT INTO THE JET AND PROBABLY COLLIDED. AT THIS POINT, A NERVOUS SUPVR CAME ON THE FREQ AND RPTED THAT THE POP-UP TARGET HAD NOW DSNDED RAPIDLY OUT OF RADAR COVERAGE. TRACON FAILED TO WARN US OF TURBOJET TFC, ON A STEADY COURSE, HDG RIGHT AT US, THEN SUGGESTED WE TURN SO AS TO COLLIDE WITH SAME ACFT. I THINK CTLRS SHOULD RECEIVE MORE TRNING IN SPATIAL RELATIONSHIPS.
