Just had a guy fatigue that was given 16 hours of rest...2 hours at the hotel on duty...show at the fbo 1 hour prior to flight...did a .9 rev leg...then fatigued.
:crying:
Just to play devil's advocate here...
16 hours of rest sounds like a major shift to the circadian rhythm, which may be what prompted that fatigue call. Also, as I'm sure you're aware, hotels are
not particularly restful places during day light hours. Maids slamming doors, footsteps shaking the hallways (more an issue in cheap hotels), and so on. So if the bulk of the rest period was in the daytime, that may be the issue.
Hypothetically, let's say I'm that crewmember who called in. I work from 10am to 11pm on this duty day. That means I got up around 8am to get ready, eat breakfast, etc., and did 13 hours of duty, and probably got settled into the hotel around midnight.
Now scheduling gives me 16 hours of rest, which means I'm coming to work at 3pm -- actually 5pm, when you add in the two hours of hotel duty. Do you really think I can just "reprogram" my body to wake up 7 hours later on a whim? I can't. And I'm going to get hungry and probably wake up long before that, because the breakfast and lunch periods from the day prior have passed while I was theoretically sleeping.
My point is, I'm going to be dog tired at midnight, and go right to bed. That means I'm probably going to get up around 8am,
regardless of the time I was scheduled to start duty. And from that point on, the clock's ticking. By dinner time, yeah, I'm probably going to be cooked, even though I "only did a .9 rev leg."
While I'm always happy to get a long overnight like that, from a productivity standpoint, I'd have been better off with 12 hours than 18 at the hotel. (36 would be even better, but that's probably asking a bit much.)
You're not going to get a full day out of me after you shift my sleep pattern, in
either direction. I'll do my best as I always do, and the quality of rest I got (i.e., was it a quiet/comfortable hotel) will have an impact on how much energy I'll have. But I'm not going to fly groggy. It absolutely isn't safe, for us or our owners.
