1. It varied. On days following a redeye-turn or other night flying, it was usually in the 5-6 hour range. On "normal" days, a little less.
I'm not sure you answered the question. I'm talking about CDO's, not redeyes or other types of night flying. On "normal" CDO's (you know something like was originally proposed in the latest TA where you fly a late night flight out and an early morning flight back the next morning with something like about 6 or 7 hours in between flights), how much sleep did you generally get during the day? i.e. During the day, did you take a couple hour power nap or did you get some serious sleep?

2. Usually layover minus an hour. Some of the hotels were very close, and conducive to the CDO. The sign in sheet and room key were in the van. In fact, only two of the hotels I can remember DIDN'T make it easy to get quickly to the room, and they weren't bad. Personally, I don't have sleep issues - which is why I liked "illegals".
So on a typical CDO where you fly a short leg and get in, say, around 11:30pm and take the 6am flight back the next morning, you got maybe about 4 hours of sleep on average?
Oh, and on a side note... how do you think they came to be known as "illegals?"

3. It varied. When I could hold them, I planned for them. I found it easier to plan for sleep, and to recover from the flying, than it was when I flew 11-12 day Asia trips. Those things messed me up for a few days afterward. With CDO's, I was getting my flying done is fewer days, and that made my planning worth it.
Thanks, but I didn't ask you about comparing the CDO with Asia trips. I asked how much total sleep you had on average in the 24 hours preceding the morning flight. If you can answer questions #1 and #2, this is easy... simple addition.

4. I think it says something about being rested. In my experience with CDO's, I felt safe, and MORE rested than I did on Day 9 of a 12-day, regardless of how much planning I did. I trust the science on WOCL. The CDO's I've flown allowed me to sleep during my WOCL's.
The sleep science specifically references 8 hours as being the amount of sleep most normal human beings need in order to function at 100%.

5. Yes.
Thank you. Any ideas why they specified 8 hours? (hint: see question #4
)

I'm not sure. Doesn't matter. If we get CDO's, I'll bid them. If we don't, I won't bid them.
I think it matters. We're trying to establish whether most pilots get adequate rest when doing CDO's. What is the track record? As far as I know, there has been no study and therefore no published data exists. I think that's relevant before we entertain adding that type of flying at Delta.
You said you did CDO's. I'm assuming you know others who did as well. I'm asking about your personal experience with how much sleep you got and what others may have told you about how much sleep they got. Did you ever have conversations with anyone else about how they handled sleeping with CDO's? If so, what did they say?
