I'll look online.

Moderate sleep deprivation produces impairments in cognitive and motor performance equivalent to legally prescribed levels of alcohol intoxication

RESULTS—After 17-19 hours without sleep, corresponding to 2230 and 0100, performance on some tests was equivalent or worse than that at a BAC of 0.05%. Response speeds were up to 50% slower for some tests and accuracy measures were significantly poorer than at this level of alcohol. After longer periods without sleep, performance reached levels equivalent to the maximum alcohol dose given to subjects (BAC of 0.1%).
I'll keep looking for more on cumulative effects.

I believe this is the study. Additional info was presented in the ppt presentation.

So you're saying that your "common knowledge" (from talking to other pilots who do CDO's, not just you) tells you that most are sleeping 8 hours a day?

Okay, let's go with that assumption for a moment. You get back home from the CDO... say 0800. Let's say you go to sleep at 0900 and sleep for 8 hours. That puts you at 1700 waking up. Report for the next night's CDO is 2100. In order to sign in on time you need to leave your house 1 hour before sign-in. So that gives you a grand total of 4 usable hours at home during the day... none of which are during normal business hours (in case you happen to be running a side business).

Explain to me again what makes CDO's so attractive? Seems like you're spending considerably LESS time at home (awake). And then there's that pesky anecdotal evidence where virtually every pilot I've ever heard who liked CDO's talked about their primary reason for liking them being all that extra time they have at home. Just not quite adding up, is it?

Here's a typical cdo stretch, start Monday 1900 report, TVC cdo, get 7 hours of sleep, get home 0800. Don't sleep at all. Report Tuesday, 2045 report, ITH cdo, get 5 hours sleep, get home 0800, nap for 3 hours. Have the next two days off, and repeat this the entire month. Very rested, very safe.

Pointing out the WOCL flying we already do isn't justifying CDOs, it's discounting the argument that we shouldn't do CDOs for safety reasons. That isn't the same thing. CDOs are undesirable flying. That's a pretty good reason not to do them. You don't have to be sensational to have a good argument. "CDOs are unsafe" is a bad argument unless you can provide some sort of evidence. There are countless airlines who do CDOs with FOQA and ASAP programs. I've never seen any data that indicates CDOs are unsafe. That data might exist. Find it and post it and I'll agree with you.

FAA definition


Being tired isn't the same as being fatigued. I fly tired all the time and I suspect everyone here does too. Yawning doesn't affect my ability to pilot an airplane.
I've done many CDO's. They are fatiguing. I know first hand. I've talked with many guys who have done them who said they felt like zombies after 2 nights of these. They said they were fatigued. Your arguments on their safety and that they only make you "tired" and we are all tired don't hold up. Sorry Charlie.

Just google Dr. Nick Davenport and/or Dr. Mark Rosekind. I was in DC last week and had this exact data presented by Mark Rosekind.

Nobody is saying the pilots lie about the data. What they are saying is data is selected which fits the scenario being "pushed." The data is still that, data.

Data doesn't become information or fact unless it is put in context. If you choose/control the context, you control the information. The data itself is meaningless unless used in the proper context...proper.

Example: all the back and forth on CDOs. One guy says nobody sleeps. One guy says he sleeps. Therefore, the nobody sleeps is invalid. If an alcoholic is in charge of making rules about drinking before flight, would his perspective be the same as a teatotaler?

Form 4 data is data out of correct context.

This may be one of the most relevant posts I've seen regarding the DALPA Flight Loss Pay Crew and company propagandists that come here including SF. There is a boatload of data. They access and extract it and likely have guys at the office help put together an argument (often to lower expectations) and selectively apply it. They try to present it boldly as a universal fact while sniggering under their breath because they know it could be flipped 180 degrees from what they are saying if they used the "other data" and interpretation that was selectively left out.

For the record, I think FPL should be banned for anyone to be posting on message boards UNLESS they state their name and position with ALPA and are willing to show their time card. Hiding behind "these are just my own opinions" while getting paid is pure nonsense and a waste of dues money that should be used to campaign for restoration.

That's sure right Ed, but don't forget they are just as scrupulous in ignoring data that would highlight our leverage. Leaving out our JV foreign competitors in contract comparisons for example.

The question I have is why? There's no question they're doing it, but why is the key. Are they doing it because they really do have an accurate pulse of the pilot group majority and this is what Delta pilots want in their union? Or is there another reason our union behaves this way?
