<< >> NASA ASRS Report 380180, September 1997

An MD80 took off from sea with the wrong radial dialed in for the departure. Flight crew intercepts wrong radial until TRACON calls and gives a vector to get back on course.

Narrative:

XY29Z, sea departure control, climb out. ATC facility: sea departure control. Location: sea. I used the wrong radial for the mountain 4 SID. SID calls for the 158 degree radial and I used the 185 degree radial. I can only attribute this to fatigue. Both I and the first officer discussed the SID prior to leaving the gate. Sea departure didn't sound too concerned but did bring it to our attention. Supplemental information from acn 380179: the captain, who was flying, had 185 degrees set in his course window instead of 158 degrees. We did not catch this error until airborne. We took off on runway 16R and then turned to a heading 185 degrees to intercept the 185 degree radial. Moments later, departure control advised us that 158 degrees was the desired departure radial and then issued us a turn to 140 intercept the 158 radial.

Title: AN MD80 TOOK OFF FROM SEA WITH THE WRONG RADIAL DIALED IN FOR THE DEP. FLC INTERCEPTS WRONG RADIAL UNTIL TRACON CALLS AND GIVES A VECTOR TO GET BACK ON COURSE.

Narrative: XY29Z, SEA DEP CTL, CLBOUT. ATC FACILITY: SEA DEP CTL. LOCATION: SEA. I USED THE WRONG RADIAL FOR THE MOUNTAIN 4 SID. SID CALLS FOR THE 158 DEG RADIAL AND I USED THE 185 DEG RADIAL. I CAN ONLY ATTRIBUTE THIS TO FATIGUE. BOTH I AND THE FO DISCUSSED THE SID PRIOR TO LEAVING THE GATE. SEA DEP DIDN'T SOUND TOO CONCERNED BUT DID BRING IT TO OUR ATTN. SUPPLEMENTAL INFO FROM ACN 380179: THE CAPT, WHO WAS FLYING, HAD 185 DEGS SET IN HIS COURSE WINDOW INSTEAD OF 158 DEGS. WE DID NOT CATCH THIS ERROR UNTIL AIRBORNE. WE TOOK OFF ON RWY 16R AND THEN TURNED TO A HDG 185 DEGS TO INTERCEPT THE 185 DEG RADIAL. MOMENTS LATER, DEP CTL ADVISED US THAT 158 DEGS WAS THE DESIRED DEP RADIAL AND THEN ISSUED US A TURN TO 140 INTERCEPT THE 158 RADIAL.
