I log all commercial flights I take as a passenger (just like I do when
I fly my Cessna).  One of the things I put in the logbook is the tail
number of the aircraft.  Often, the tail number is not easily visible at
the gate, but most airlines put a number on the forward fuselage or gear
doors that is enough to figure out the tail number.  For example, an AA
MD80, N508AA, has "508" by the cargo door.  AS puts the number above the
windscreen.

On AA 757's, some of the gear door codes are as described.  Others use a
code such as "5CX" (which is N681AA).  Can anyone tell me how to figure
out the tail number from the "5xx" code that AA uses?

Thanks!!
