It is in 20-K-6-g relative specifically to short call assignments. I can't find any similar reference for field standby. Interestingly, I called the crew desk (risky, I know) and they verified I was released from the end of my field standby block until the beginning of my next long call assignment. (0001 tomorrow.) Not sure if this was a scheduling error, but I guess it's on the tapes for today, anyhow. If anyone can reference the contract for field standby reverting to long-call, I'd be interested.
