Re: JetBlue Fatigue Experiment

Northwest did some fatigue research almost 20 years ago for NASA on long haul flights. It was indeed FAA approved well in advance.

It concerned allowing pilots to sleep for about 45 minutes while in the cockpit seat. However, all these cases were with three pilot cockpits.

The results showed more alert pilots during decent and landing with a so called "NASA Nap" during the cruise portion.

Flying 10 hours (flying time) may or may not be a fatigue issue (IMO). If it's 10 hours with 8 legs, that would be close to a 16-18 hour duty day. Yup, a lot of potential fatigue.

If it's 10 hours with (for example) just two legs and perhaps a 12-13 hour duty day, that might not be so prone to fatigue.

And, of course, it depends upon when the flight periods start. If they are off you normal sleep cycle, that clearly it's likely to have more fatigue issues (IMO).

Enough of this, I'm off for a "NASA Nap".
