Narrative:

While flying the worth 3 departure tcc transition, aircraft last assigned clearance was a 250 degree heading to intercept the TTT 275 degree radial to rejoin the SID. With aircraft passing approximately FL190 in a climb to FL220 and in a right turn intercepting the TTT 275 degree radial, departure control gave a further right turn to intercept the TTT 275 degree radial. Aircraft was approximately at 36.6 DME with VOR #1 indicating approximately 1.5 degrees south of course and intercepting and the VOR #2 at approximately 3.0 degrees left of course and intercepting. ATC stated that there was no problem and that the further right turn was issued as a precaution to help to ensure that a potential problem did not develop.

Original NASA ASRS Text

Title: ATC ISSUES A SECOND VECTOR HDG TO ENSURE THE ACFT TRACK WOULD INTERCEPT THE PLANNED COURSE.

Narrative: WHILE FLYING THE WORTH 3 DEP TCC TRANSITION, ACFT LAST ASSIGNED CLRNC WAS A 250 DEG HDG TO INTERCEPT THE TTT 275 DEG RADIAL TO REJOIN THE SID. WITH ACFT PASSING APPROX FL190 IN A CLB TO FL220 AND IN A R TURN INTERCEPTING THE TTT 275 DEG RADIAL, DEP CTL GAVE A FURTHER R TURN TO INTERCEPT THE TTT 275 DEG RADIAL. ACFT WAS APPROX AT 36.6 DME WITH VOR #1 INDICATING APPROX 1.5 DEGS S OF COURSE AND INTERCEPTING AND THE VOR #2 AT APPROX 3.0 DEGS L OF COURSE AND INTERCEPTING. ATC STATED THAT THERE WAS NO PROB AND THAT THE FURTHER R TURN WAS ISSUED AS A PRECAUTION TO HELP TO ENSURE THAT A POTENTIAL PROB DID NOT DEVELOP.
