high-speed overnight
n.— «If you do not have at least 8 hours off between duty periods then it’s not rest, it’s duty, so you’d stay on duty all night long (even if you happen to go to a hotel for a few of those hours). This is referred to as a continuous duty overnight (CDO) or a high-speed overnight or a stand-up overnight. As others have explained, you’d fly outbound for a leg or two arriving at the out-station pretty late. You’d go to the hotel for a few hours and a nap then come out and fly the first flight out in the morning. You’d fly a leg or two into the hub then would have your “rest” during the day and would return again that night to do it again.» —“Re: Comair 191″ AVSIG Aug. 30, 2006.
