Assuming a NB: release + 9 hrs (free of duty) then 24hrs for every X day that was violated.
if you release < 1500, then the next day will show as a PR, which is a partial PB.
Classic examples using two common 1-day GS:
1) A morning ATL turn that got broken off of a longer trip so it could be assigned to a day 1 res pilot. Let’s say it checks out at 1330. Add 9 hours so your X days start at 2230. For ease we’ll say that your next day was LC. Your schedule will have a PR with an end time of 2230 then next day.
2) An island turn that releases at 1830. Counting 9 hours out your X days start at 0330. In this case that next day will show on your schedule as PB, and the day after that shows as a PR ending at 0330.
It’s all dumb looking like that because DBMS can’t start an X day at any time other than midnight so the PB/PR workaround was found. It’s weird, but once you’re used to it you can really work some of it to your advantage.
