Narrative:

The problem arose due to the departure controller asking for a nonstandard departure heading for the runway 13L jet departures. Air carrier a was departing runway 13L on a heading of 140 degrees and air carrier B departed runway 13R on an initial heading of 185 degrees. Since the runways are 1 mi apart and staggered, the runway 13L departure turning right should never be a factor for the runway 13R departures. The problem was air carrier B, the second departure, flew runway heading and ended up 1 1/2 mi behind air carrier a.

Original NASA ASRS Text

Title: 2 ACR ACFT, DEPARTING FROM PARALLEL RWYS AT JFK, FLY RESPECTIVE HDGS WHICH LEADS TO POSSIBLY CONVERGING GND TRACKS WHILE AT SIMILAR ALTS.

Narrative: THE PROB AROSE DUE TO THE DEP CTLR ASKING FOR A NONSTANDARD DEP HDG FOR THE RWY 13L JET DEPS. ACR A WAS DEPARTING RWY 13L ON A HDG OF 140 DEGS AND ACR B DEPARTED RWY 13R ON AN INITIAL HDG OF 185 DEGS. SINCE THE RWYS ARE 1 MI APART AND STAGGERED, THE RWY 13L DEP TURNING R SHOULD NEVER BE A FACTOR FOR THE RWY 13R DEPS. THE PROB WAS ACR B, THE SECOND DEP, FLEW RWY HDG AND ENDED UP 1 1/2 MI BEHIND ACR A.
