Narrative:
Low ceiling, 45-60 min departure delays, and numerous gars on ILS runway 4R approach due to ny TRACON running arrs at minimum separation and not allowing for previous arrs to slow to approach speed. A B737, aircraft #2, on approach runway 4R, announces a missed approach on 3 NM final. A B727 (aircraft #1) on departure roll runway 4L. Aircraft #1 was a low and slow departure, #2 was at a high airspeed. #1 was instructed to fly runway heading 040 degrees, maintain 2000 ft, #2 was instructed to turn right heading 070 degrees, maintain 2000 ft (separation: diverging headings and at least 1 mi horizontal). Both planes were switched to departure. The ny TRACON departure controller turned #1 to heading 060 degrees, and #2 came within 1 1/2 NM behind him, same altitude. Note: when I tried to coordinate the missed approach with the departure controller, he said to give #2 the 'standard missed.' I told him unable, that #1 would be on runway heading. He said, 'do what you have to do.' we were both too busy to properly coordinate. Also, this situation (departure and missed approach) has resulted in numerous operrors and ucr's.
Original NASA ASRS Text
Title: RPTED LOSS OF SEPARATION WHEN THE DEP CTLR TURNS A DEPARTING B727 ON RWY HEADING TOWARD THE DIRECTION OF A B737 ON A VECTORED MISSED APCH WITHOUT THE APPROPRIATE LATERAL VERT SEPARATION.
Narrative: LOW CEILING, 45-60 MIN DEP DELAYS, AND NUMEROUS GARS ON ILS RWY 4R APCH DUE TO NY TRACON RUNNING ARRS AT MINIMUM SEPARATION AND NOT ALLOWING FOR PREVIOUS ARRS TO SLOW TO APCH SPD. A B737, ACFT #2, ON APCH RWY 4R, ANNOUNCES A MISSED APCH ON 3 NM FINAL. A B727 (ACFT #1) ON DEP ROLL RWY 4L. ACFT #1 WAS A LOW AND SLOW DEP, #2 WAS AT A HIGH AIRSPD. #1 WAS INSTRUCTED TO FLY RWY HDG 040 DEGS, MAINTAIN 2000 FT, #2 WAS INSTRUCTED TO TURN R HDG 070 DEGS, MAINTAIN 2000 FT (SEPARATION: DIVERGING HEADINGS AND AT LEAST 1 MI HORIZ). BOTH PLANES WERE SWITCHED TO DEP. THE NY TRACON DEP CTLR TURNED #1 TO HDG 060 DEGS, AND #2 CAME WITHIN 1 1/2 NM BEHIND HIM, SAME ALT. NOTE: WHEN I TRIED TO COORDINATE THE MISSED APCH WITH THE DEP CTLR, HE SAID TO GIVE #2 THE 'STANDARD MISSED.' I TOLD HIM UNABLE, THAT #1 WOULD BE ON RWY HEADING. HE SAID, 'DO WHAT YOU HAVE TO DO.' WE WERE BOTH TOO BUSY TO PROPERLY COORDINATE. ALSO, THIS SIT (DEP AND MISSED APCH) HAS RESULTED IN NUMEROUS OPERRORS AND UCR'S.
