Six starts with no 24 hour break will place you in FR status for 48 hours. Seven starts will trigger 72 hours FR. If you are tied up for 24 hours and 1 minute, your clock is reset. If you double in a calender day, that is considered two starts.
If you deadhead separate and apart, this does not reset your clock. Nor is it considered a start. It simply doesn't count toward triggering a FR status.
If you spend over 24 hours at your AFHT, your clock is reset.
Any covered service under the HOS counts as a start. If your call is broken after you are on duty, etc. If your Federal tie-up uses line A, with time on duty shown, it is considered a start.
The accumulation of Limbo time remains unchanged. Of course, the Carrier's first comment was that FR will still be considered a layoff when considering a bonus day for the extra board. Please continue to submit timeslips for these.
