747 measurments

No official documents, but hand-measured, the axis of the column is 13.5" from the side of the thrust quadrant (not pedestal). The thrust quadrant is 15" wide. The other column is 13.5" from the other side of the thrust quadrant.

This equates to 13.5 +15 +13.5 = 42"

This should be confirmed independently from other sources, of course. Please note that a PS1 user used my measurements (with my approval) to make some very nice diagrams which have subsequently been circulated on the internet, so other sources may not be as independent as they seem ;)

Thanks John :) Gary was also kind enough to measure in his sim, he got 112cm.

Interesting. 112cm is 44.09 inches. I'm pretty sure my measurements were not 2 inches in error. Where did  Gary  get his measurements from, I wonder  :?

For interest, the thrust levers are not centered on the quadrant. The levers are offset towards the captain.

P.S. Gary, is the pedestal located in the centre of the aircraft?

I believe Gary measured the distance between the centre of the yokes themselves.

I would trust John and Farrokh's measurements of 42 inches.

 I did it again and it's actually 108 between the center points which means I'm within half inch.  I think mine may be a little bit wider apart due to the mechanism.  Anyway no one has noticed yet :). Each yoke is in the middle of the captains PFD.

 You know britjet and macaba are going to turn up to my sim with tape measures next time don't you!! Anyway what's half an inch between friends  ? :shock:

Cheers

My reference points were also the centre of the yokes : :mrgreen:
