Narrative:
We were in published holding at la grange VOR (3 turns). Now we are cleared out of holding. We receive a couple of vectors, then are cleared direct lgc and then the lgc arrival. Since we already passed lgc (entering holding), we cannot program the FMS to go direct to lgc. It doesn't matter that we are 25 mi from the VOR (to the southwest). Once we pass lgc, the computer drops it from the waypoint list, and you cannot re-enter it. So, the captain dials in the VOR, and he tracks the direct radial to it. Now, he wants the FMS to navigation the remainder of the arrival. So, he has to go back to lateral navigation mode (from heading) and go direct to the next point on the arrival. Here's the mistake. He put in husky for next point. Husky is on the sinca STAR (approachs atl from southeast). The point he wanted was honie. So the track to husky takes us south of the arrival. Approach sees us deviating right of course, and vectors us back to arrival. I noticed the distance to atl was 65 mi or so, as displayed by the FMS. That didn't seem right (too much by 15 mi or so), but I didn't pursue that, which of course, I should have. Only after we were vectored back to arrival did I catch the waypoint error (captain didn't catch it). Here are some factors, in my mind, concerning my lack of aggressiveness when something just didn't seem right: 1) I was very tired -- end of a 3-DAY trip, and had been woken up both of the previous nights by a call from the company. 2) CRM in the L1011 is marginal with a lot of the capts. In fact, the first couple of legs with this guy, he was doing a lot of instructing to me. This, wrongly I know, causes me to disengage a bit when he is flying. The old guys on the L10 have lots of experience, of course, but I'm not a 'greenhorn' either (flying for 20 yrs, 11 with the airline). The capts rarely ask for crew input, so if you're not flying, the mind wanders (especially when tired).

Title: L1011 CREW HAD TRACK DEV ON ARR TO ATL.
Narrative: WE WERE IN PUBLISHED HOLDING AT LA GRANGE VOR (3 TURNS). NOW WE ARE CLRED OUT OF HOLDING. WE RECEIVE A COUPLE OF VECTORS, THEN ARE CLRED DIRECT LGC AND THEN THE LGC ARR. SINCE WE ALREADY PASSED LGC (ENTERING HOLDING), WE CANNOT PROGRAM THE FMS TO GO DIRECT TO LGC. IT DOESN'T MATTER THAT WE ARE 25 MI FROM THE VOR (TO THE SW). ONCE WE PASS LGC, THE COMPUTER DROPS IT FROM THE WAYPOINT LIST, AND YOU CANNOT RE-ENTER IT. SO, THE CAPT DIALS IN THE VOR, AND HE TRACKS THE DIRECT RADIAL TO IT. NOW, HE WANTS THE FMS TO NAV THE REMAINDER OF THE ARR. SO, HE HAS TO GO BACK TO LATERAL NAV MODE (FROM HDG) AND GO DIRECT TO THE NEXT POINT ON THE ARR. HERE'S THE MISTAKE. HE PUT IN HUSKY FOR NEXT POINT. HUSKY IS ON THE SINCA STAR (APCHS ATL FROM SE). THE POINT HE WANTED WAS HONIE. SO THE TRACK TO HUSKY TAKES US S OF THE ARR. APCH SEES US DEVIATING R OF COURSE, AND VECTORS US BACK TO ARR. I NOTICED THE DISTANCE TO ATL WAS 65 MI OR SO, AS DISPLAYED BY THE FMS. THAT DIDN'T SEEM RIGHT (TOO MUCH BY 15 MI OR SO), BUT I DIDN'T PURSUE THAT, WHICH OF COURSE, I SHOULD HAVE. ONLY AFTER WE WERE VECTORED BACK TO ARR DID I CATCH THE WAYPOINT ERROR (CAPT DIDN'T CATCH IT). HERE ARE SOME FACTORS, IN MY MIND, CONCERNING MY LACK OF AGGRESSIVENESS WHEN SOMETHING JUST DIDN'T SEEM RIGHT: 1) I WAS VERY TIRED -- END OF A 3-DAY TRIP, AND HAD BEEN WOKEN UP BOTH OF THE PREVIOUS NIGHTS BY A CALL FROM THE COMPANY. 2) CRM IN THE L1011 IS MARGINAL WITH A LOT OF THE CAPTS. IN FACT, THE FIRST COUPLE OF LEGS WITH THIS GUY, HE WAS DOING A LOT OF INSTRUCTING TO ME. THIS, WRONGLY I KNOW, CAUSES ME TO DISENGAGE A BIT WHEN HE IS FLYING. THE OLD GUYS ON THE L10 HAVE LOTS OF EXPERIENCE, OF COURSE, BUT I'M NOT A 'GREENHORN' EITHER (FLYING FOR 20 YRS, 11 WITH THE AIRLINE). THE CAPTS RARELY ASK FOR CREW INPUT, SO IF YOU'RE NOT FLYING, THE MIND WANDERS (ESPECIALLY WHEN TIRED).
