What\'s the difference?

On the last 2 numbers an airplane model number(757-2 23 ), what do they do differently to each model to have a 23 compared to a 757-2 B7? And the same question goes for all the other airplanes, not just the 757. Do you get my question?
 
Re: What\'s the difference?

Hello,

The "23" is the code for American Airlines and "B7" is for US Airways. Each airline has its unique code. Another example is Delta in which there code is "32." Hence you have a Boeing 757-232.

Hope this helps


Edit: Spelling error

Yeah, I never got that until now. Thanks!
 
Re: What\'s the difference?

Off topic here, but how can you tell the difference for example between a 737-500 and -600? Or how about 767-100 and -300? And so on. Or is it very difficult to spot it out?

I can only tell if it is a 737,757,etc. but not the -300,-500,etc. part of the model #. I can only find that out by looking online.
 
Re: What\'s the difference?

Well, first of all, I don't think there was a 767-100, at least for commercial use (please correct me if I am wrong). You can tell the difference here (at least that’s how I decipher them) is by looking at the aircraft length. For the 737NG series, you can usually tell the difference by looking at its length with the -900 being the longest. The -500 and -600 are tricky. I think to tell the difference between these models is with the position of the doors?

Sorry I cannot be of much help here. Perhaps someone else will write with a better explanation.

Re: What\'s the difference?

This website says"The Boeing 767-100 was a shorter 180/190 seater intended as a competitor to the Airbus A310, it's similarity to the B757 led to the cancellation."

I really didn't know if there was a -100 made but I decided to write it because there might have been a chance there is one.

Thanks for your response.

The 737 "classic" series is quite similar to the "new generation. The 737-500 is characterized by:

powerplant: 2 General Electric/SNECMA CFM56 turbofans
seats: up to 170 passengers (737-400)
cruise speed: 440 kts
distinctive features: large engine intakes are flattened at the bottom for ground clearance, not perfectly circular like most turbofan engines

the 737-600 is characterized by:

powerplant: 2 General Electric/SNECMA CFM56-7B
seats: up to 177 passengers (737-900)
cruise speed: 440 kts
distinctive features: looks very similar to "classic" 737 series; wingspan is nearly 8 feet longer, tail 5 feet taller, aircraft sits nearly 18" higher on the main gear so that the engine intake shape is more nearly rounded than 300/400/500.

Re: What\'s the difference?

go to airliners.net and study the pictures but avoid the forums. I used to look at that website 24-7, and I am now pretty good at telling the differences in the boeings and airbuses. Of course only do this if you really care how to tell the difference, or in my case if you have nothing better to do.
