That's what I was trying to say in my previous post. The way I read the contract, a LC reserve assignment does not have to commence within one of the windows. That's the reason for the 9/12 rest period. If that was the case, an L2 pilot could, by definition, never get used unless pre-notified. If you were called between 0700-0900, 12 hours later would be outside of your window. So therefore the 12 hour call out would be redundant and impossible. It would have to be a 24 hour call out and/or a prenotify-only reserve pilot. and the L1 window would be legal to report for just 1 hour per day. That would make a Long Call pilot completely useless.
