Still learning. So for my own stupid reasons, I had a ys in as first to fly on res day. Instead got assigned SC starting at 0400 and running till 1600 (next day is a golden day). At 05 still on SC. Little later check sched and I'm on a trip that gets in around 1900. Sched calls (side note, now know why all pilots hate scheds) and is somewhat shocked when I ask how it's legal to run me 3 hours past my sc window. Huffily offers to look it up. Does so and reads a bunch of numbers at me that sum up to me being legal (can fly) till 2000.

Is that true?

(I will read the PWA, but I find it a legal substitute for ambien)
