Narrative:

This is a report to highlight a very fatiguing trip. This trip flies like an all-nighter; only it isn't. It starts out late afternoon on day #1 with a late afternoon departure. You wake up at normal time on the day (XA30) because on paper the trip doesn't look that terrible. It has 3 legs ending up on the west coast post XR05 (scheduled XR45 in this case because we were late). This puts your body landing at XT45 domicile time; after 3 legs and a 12 hour duty day. Absolutely horrible and fatiguing. I was tired before taking off on leg #3; but did not feel fatigued. The full brunt of very late body clock time and a long duty day (and long waking day) hit me full in the face during cruise on the last leg. It was at this time I realized how fatigued I was. I couldn't remember our call sign even after having answered about 30 radio calls. I was channeling my attention and couldn't gain any situational awareness. After an uneventful landing; I tried to get some much needed rest. I went to bed about XS45 and tried to make it a normal night. But your body wakes up when it wants to wake up; and mine did at XA30; after less than 4 hours sleep. This trip then continues with a late start (XM00) and finishes up post-flight again central daylight time. I feel this is a very fatiguing trip and we should get rid of it and others like it. The first 2 legs would have been fine; or 1 leg with a late arrival would be tolerable; but this trip is bordering on dangerously fatiguing.

Narrative: THIS IS A RPT TO HIGHLIGHT A VERY FATIGUING TRIP. THIS TRIP FLIES LIKE AN ALL-NIGHTER; ONLY IT ISN'T. IT STARTS OUT LATE AFTERNOON ON DAY #1 WITH A LATE AFTERNOON DEP. YOU WAKE UP AT NORMAL TIME ON THE DAY (XA30) BECAUSE ON PAPER THE TRIP DOESN'T LOOK THAT TERRIBLE. IT HAS 3 LEGS ENDING UP ON THE WEST COAST POST XR05 (SCHEDULED XR45 IN THIS CASE BECAUSE WE WERE LATE). THIS PUTS YOUR BODY LNDG AT XT45 DOMICILE TIME; AFTER 3 LEGS AND A 12 HR DUTY DAY. ABSOLUTELY HORRIBLE AND FATIGUING. I WAS TIRED BEFORE TAKING OFF ON LEG #3; BUT DID NOT FEEL FATIGUED. THE FULL BRUNT OF VERY LATE BODY CLOCK TIME AND A LONG DUTY DAY (AND LONG WAKING DAY) HIT ME FULL IN THE FACE DURING CRUISE ON THE LAST LEG. IT WAS AT THIS TIME I REALIZED HOW FATIGUED I WAS. I COULDN'T REMEMBER OUR CALL SIGN EVEN AFTER HAVING ANSWERED ABOUT 30 RADIO CALLS. I WAS CHANNELING MY ATTN AND COULDN'T GAIN ANY SITUATIONAL AWARENESS. AFTER AN UNEVENTFUL LNDG; I TRIED TO GET SOME MUCH NEEDED REST. I WENT TO BED ABOUT XS45 AND TRIED TO MAKE IT A NORMAL NIGHT. BUT YOUR BODY WAKES UP WHEN IT WANTS TO WAKE UP; AND MINE DID AT XA30; AFTER LESS THAN 4 HRS SLEEP. THIS TRIP THEN CONTINUES WITH A LATE START (XM00) AND FINISHES UP POST-FLT AGAIN CENTRAL DAYLIGHT TIME. I FEEL THIS IS A VERY FATIGUING TRIP AND WE SHOULD GET RID OF IT AND OTHERS LIKE IT. THE FIRST 2 LEGS WOULD HAVE BEEN FINE; OR 1 LEG WITH A LATE ARR WOULD BE TOLERABLE; BUT THIS TRIP IS BORDERING ON DANGEROUSLY FATIGUING.
