Coming off an X day, you are obligated to check your schedule at 1500 to before 0200 BASE TIME (The Reserve day following your last X day). If you are on a Vacation Day, no need to and this does not apply.

You are always on Long Call Status, unless they convert you to SC or give you a trip (FDP). You need at least 10 hours REST (12 hours if the start of SC or FDP is 0200-0559) before the start of SC or FDP.
i.e. If you have not acknowledged your assigned SC or RDP by 10 hours to go (12 hours for 0200-0559), you are not legal to do it.

You are always on Long Call. You are only obligated to check your schedule every NINE (9) hours via computer or VRU..Its time stamped.

If in this 9 hour check, there are no assignments, you can shut your phone off until the next 9 hours. i.e. Im on LC and at 1000 I check my schedule via icrew but I am not assigned anything so I shut my phone off for 9 hours. At 1900 I am obligated to check my schedule.

In other words. Long Call Pilot is on a 12 Hour Leash but is only obligated to check his schedule every 9 hours and acknowledge it no later than 3 hours before the start of an FDP. Or acknowledge a SC assignment no later than 1 hour prior to SC.

Also, when you are given a REST PERIOD, you have to acknowledge no Later than 6 hours AFTER THE REST BEGINS. Then you can turn everything off.

One important note, a LC pilot has no obligation of responsibility for contact during the 12 hour immediately prior to scheduled report time of rotation or 10 hours prior to start of ASSIGNED SC.

I hope this helps. This is what I come up with by looking over the 117 notes and literature.
