Some of what I typed in the first one didn't some thru, not sure why. It was supposed to say unforeseen minor delays, such as a 5 minute delay due to WX or ATC delays... Some airlines try to push the under 30 minute delay on their pilots, but technically, concurrence is required. Have never flown with anyone who wasn't willing to do it.

As to the second point, if you sign the block, but then are delayed past FDP, concurrence must happen. Meaning that when you sign, you are saying you are good. But a delay after the point doesn't mean the company can force you to go.

Thirdly, I understand it just fine. Spent most of my life interpreting regs. 117 does not protect pilots from company investigations if the company deems it necessary. That is all. You are the only one who mentioned pressure and investigation in the same sentence.

More sensical, thank you. There is (behind the scenes) a lot of contention in this arena. I simply wish the Feds had never introduced the idea of 'commander's discretion'. This is highly controversial in other parts of the world that have already introduced this concept.

Slippery slope.
