Now for some more clarification......I mean confusion!
I didn't know CAL was flying 767-400s.....
But at DAL, the -400 is a separate bid status (Tell me if I'm wrong, DAL guys). Still the same type rating (according to the FAA), but separation for bidding purposes: -400 guys only fly -400s. They are, obviously, very senior.
I know my company has looked at the 767-400, and said that if we bought it, the 757/767 could become two separate bid statuses, instead of the one it is today.
Right now 75/76 guys are qualified on all versions, but what you fly depends on your bid status. If you're a DFW domestic type you fly a lot of 757s; if you're a MIA international type you fly a lot of 767-300s deep south. Very different airplanes, but all the same in the FAA's eyes.
For type rating trivia, rumor has it the 737-800 did not get the 777 overhead panel because the Feds wouldn't consider it a common type rating with older models. Many airlines would not cough up the dough for new type-rating training courses, so Boeing left the old-style switches and dials instead of "Auto" everything on the overhead panel.
Anyone on a 737-800 who finds themselves at cruise futzing with the fuel, pressurization, cabin temp or electrical system can thank their lucky stars that the feds didn't let them fly Boeing's newest overhead panel! Having everything done automatically would be much worse than trying to land a 767-300ER at night in Sao Paulo after only flying 757s for the past month! Right? The FAA says so, right?
