What do these numbers mean?

I'm here killing some time here at Logan watching planes push back while my ride is "caught in traffic." My brain began to wonder and i was wondering what the numbers on the outside of the landing gear represented

That is the aircraft number, so the aircraft in the picture would be N310AT.

Not always.

Our "freedom" planes are N601?? on the back, I have no idea what the tail is, but the ship is 951 and those are the #'s on the front, MX can, and cockpit. Everything else in the fleet (Northwest purchased) is some sort of N9??XJ

True, AirTran has some wacky numbering correlation on their early 737s between both the registration sign and the order of addition to the fleet. "310" is registered as "N184AT."

United, for example, uses a four-digit number, where the first two digits are an equipment coding (e.g., "27xx" might be an international config. 777, while "22xx" is domestic seating (I think)). The last two digits are the last two digits of the numerical portion of the registration. American uses a totally different alphanumeric three-character system; the first character is the fleet code, the next two are serial identifiers (they changed schemes a while back, so some fleets have a mixed identifiers).

(Oh god! I just outed myself!)

Do you have any with an XJ? AirTran used to be a Mesaba company (or visa versa) before Valuejet needed a name change. Some of our old timers still have FOM's with covers that read something something "an Airtran company".
