Can anyone answer this....?

[Trevor Hale]

Ok, so I gather that the 737-700 has different Models.

could someone explain to me the difference between the 737-7CT and the 737-76N

Any takers?

[Bob Reed]

First are these models for the same airline? If so I would think it is a differant engine or avionics package or both.

[Trevor Hale]

Yes, from the same airline...

[Michael Carter]

Westjet probably leased or purchased aircraft from Capital Aviation.

Maybe vice-versa. It's not likely that the two are identical unless both are owned by the same holding company.

[Trevor Hale]

Interesting that you know the Airline I was referring to was WestJet though..

LOL.. Sometimes you scare me with the knowledge you have Mike.

So, is there any way to find out what the difference is? Or not likely?

Trevor,

I'm sure Michael do have this link:

http://www.aerospaceweb.org/question/planes/q0048.shtml

and then check this link:
http://www.jetphotos.net/census/ where find more info about the specific aircraft.

[Michael Carter]

Here is Boeing's customer code list:

http://www.airlinecodes.co.uk/boeing.asp

There is virtually no way of knowing how the two aircraft are equipped or how they are different. The airlines keep these codes as Boeing assigned them for maintenance and fitting-out purposes.

Even if another airline buys or leases the aircraft, Boeing will know what is installed and how it is configured regardless of who currently owns or operates it.

A good example of different codes within an airline is Air New Zealand.

Mainly all the aircraft end in -19. However, the 747's are different as we have some with GE engines and some with RR.

Otherwise all the other aircraft (apart from leased aircraft from other airlines) have the same -19 ending e.g. 777-219ER.

Guys thanks all for your help. I was unaware that aircraft had that kind of numbering scheme based on who it was built for.

I personally thought the different numbers meant different features..

Needless to say thanks to all, for your help and input.
