I have a question about the manuals. I see that in the PDF that came with the NGX some tables numbers are in kg and meters,but other places lbs and feet is used. I confused about this.Specifically the FCOM 1 page 707. 737-800 . Kg is used in the PDF. How are the printed manuals?Anyone who can explain the cross use of pounds and kilos? I would think that either one or the other,or both would be the better way to go. Anakin Diaz
