Reserve pilots get their 10 hours after completing a reserve availability period which is, again, considered their FDP. Flica says FDP during and after a flight assigned to a reserve pilot because that's how the system works. It doesn't mean they're extending anything. Just something they have to put in there to make old technology work right.
This was also said in the ALPA call. They sounded a little surprised that anyone would even think they didn't have to answer their phone on reserve after completing a flight.
FAR 117 does NOT consider a Reserve Availability Period to be part of the Flight Duty Period unless it is Airport/Standby Reserve. This is clearly stated in the regulations. However, to continue to use you after you have started flying for the day, they do have to keep the FDP clock running in between flights or possible flights in order to stay legal.
In the case they keep the clock running, they have to release you to a minimum 10 hour rest period once the max FDP from table B is reached, regardless of how much longer you have to go on your original RAP. Your RAP+FDP cannot exceed Table B plus 4 hours, nor exceed 16 hours total.
That is why they will put you on FDP status with an ending time that matches the max FDP from Table B. That may be different than your original RAP end time.
