In all honesty, it comes down to are you willing to walk away from your job because of it. Not to toot my own horn, but I walked into unemployment over it (at least for a bit).

The problem with Part 135 is often times it is a first "real" job for people. All they know is either flight instructing or 91 stuff and have never bothered to look at or be taught 135 rules and regs. I know I wasn't aware of all this stuff when I first started. My first day of indoc that this came up, the now all too familiar "grey area" conversation comes up. Of course no mention of LOIs. I learned the hard way by figuring out first that this lifestyle sucked (on call 24/7) and that leading to wondering why it was allowed to be so. Come to find out it isn't and hasn't been for quite some time (many LOIs).

This is often the first question I have in interviews when it's my turn for questions. How do you determine and record rest?

I wholeheartedly agree that we need to get the word out on this, but it must start at the student level. Flight instructors need to know this and at the very least inform students that LOIs exist about many things, not just 135 rest rules.
