I just made two frames for the PFD / ND using the measurements in the front section build guide drawings. However, when I displayed the screens behind it I could not get them to fit properly. The displays seem to be a square and the drawings in the front section guide are a bit wider / lower 187x170 ID if I got the measurements right.
I checked the 737 measurements document and according to that the ID for the PFD/ND frame should be 180mm x 180mm. So that would fit with the square display. Are the PFD/ND sizes in the front MIP guide intentionally tweaked to fit a screen or something like that or is it a mistake somewhere?
