But in both cases the angle of contact will pull the gear leg to the left, which is behind the CG, therefore stabilizing the plane in yaw. And in neither case would the leg twisting moment be greater than the other, at last for any reason that I can see.
That’s the best explanation to something
I pondered for some time
However, having flown the 757 with a
trailing bogie and the 767 with forward
‘trail’ I can tell you the latter is far less
forgiving
The design seems to magnify touchdown
forces!
I suspect the same happens on the A380
and perhaps the A350
