Holy crap RC! Extended duty to 16 hours. What sort of FRMS do you work under? I'm guessing (hoping) split shifts.
The whole crew meal thing, (at least for RPT carriers) came about, and continues to this day as an alternative to regular crew breaks. The ironic thing is, crew meals in themselves do not mitigate fatigue. It's for this reason that many crews place an emphasis on not only their edibility, but quality as well.
As far as I'm concerned, given the choice I wouldn't touch them, too many variables. I would much prefer adequate breaks during a duty. If the companies who provide many of these poor excuses for nutrition were serious about fatigue, then they would too.
I'll wait for Hell to freeze over!
