Why do B737's taxi skew?
I was following an SAS 737 the other day, close behind, possibly number 11 for departure, and the B737 had his nose wheel on the yellow line, and yet the aircraft was extremely skew all along the lengh of taxi. By measure of the distance between each of the main gear and yellow line, it was close to one third and two thirds difference between them, meaning the aircraft must be taxying as much as 10 degrees-12 degrees off centerline heading. Taxi way heading was 272 degrees (opposite of line up runway) and I would say this guy had a heading of 285, whilst tracking 272. Very clearly I thought the right main gear was not tracking straight, but rather tracking inboard. I have observed many other B737's and they all seem to taxi skew, however, on this occasion is was very obvious. Any idea's why they built the B737's like this?
