A-320 undercarriage
All of the A-320s I know of, have one wheel on each side of the the main undercarriage. I was reading the march 2008 edition of airliner world, and in the middle of pg 22, there is an A-320 that has two wheels on each side. Why is this? I know that Jetstar and any other A-320 operator that I've seen only have one wheel. The aircraft registration is VT-EPK. You can search it on airliner.net and you will notice what I'm saying.
I hope this isn't a stupid question.
Thanks in advance.
