new A/C information

[Mr.HP]

Hi,

I'm in Beginner's World, so I can browse information of new A/C at that time (year 2000). I want to do research on plane from other time (prior and post 2000), so where can I find the data?

Also, I noted that the new A/C, say the new standard B734 burns the same amount as the 10 year old standard B734 (2880 kg/hr). Is it true? Or the information there is for reference only

The maintenance cost are different, btw

Thanks
