To add onto my previous post, it's not as simple as taking off from JFK and flying to SEA. That's not an equivalent time but there are physical and psychological challenges when you're crossing time zones east, in the middle of the night.
Sure, in a controlled environment like a flight simulator you can make it work, but when you're dealing with the real world and not "Sim World" where you're struggling to understand heavily accented English, dealing with different rules, the sun's smack dab in your face and your eyeballs say 0800 but your body says 0300 and you're not sure if you were given direct Compton or Koksy, or was that a radar heading for Maastrict or were we supposed to join upper-lima 567, having a fresh pilot in that seat is handy as hell. Oh crap, what did the 10-1P page say about expecting issuance of RTA times. Was there a slow-down point? Oh yeah, we're outside of RVSM airspace in Eastern Europe, what was eight-thousand, one-hundred meters standard on the conversion chart?
When the real work starts, your body is already ready to shut down unless you're rested.
So you're pounding coffee all night in order to chemically keep yourself alert. Guess what, that caffeine in your system will absolutely wreck your sleep opportunity the next day so chances are, you won't be able to properly rest for hours after arrival. Now you're going to wake up late, try to find some dinner and now you find yourself awake, unable to sleep to catch proper rest for your flight back the next day.
No worries, if you say "Hey! I'll fly relief, I'll take first break"... There isn't a first break. It's just you and the other guy in the cockpit, bone tired.
Sadly, if we flew to the FAA's new rules, our non-union flight attendants have a better crew rest policy than our unionized pilots.
Have you, personally, experienced any of the above? If not, what qualifies you to lecture me about how the new work rules would affect me in my side of the operation?
