There are only 41hours recorded for 12 flights of this "AA77" FDR.
41/12 makes it ~ 3.5 hours per flight, right?
Strange eh? Assuming you cant fly 3700 km (~ 2300mls) in 3.5 hours with a 757 at 530 miles/hour top speed.
Was the airliner N644AA constantly assigned to the AA77 flight from Washington to LAX? (and back?) If so, the presented FDR is not from AA77.
If the N644AA (aka N5BPAA) was not constantly asigned to AA77 - you can't assume it to be doubtable, the cabin door has been closed over the average 3.5 hours per flight.

Are there any meals served for the pilots on a 3.5 hours flight?
Are there meals served at all on such short hops?
Do you have to use the lav within 3.5 hours leaving the airport?
A female pilot probably...
The FDR is off, as long as the engines are not running. The pilots enter the flight deck before starting the engines and they shut them down before leaving the flight deck.
=> They open the cabin door, but the FDR doesn't read it. No beaming necessary.
