1. ## 737 Window measurements

I'm looking for the angles between the cockpit windows in the horizontal plane. So in a top view, what are the window angles relative to each other?

2. Give a look at Ian's site:

http://www.737ng.co.uk/shell.htm

and here

I am building them too and they are extreemly difficoult,so be prepared......

3. I'll second that!

4. Those are the drawings I based my question upon. You see them on Marcus' site and in the download area of this site as well. They describe the measurements of the individual windows, but not how they are positioned relative to each other. The only thing you know is that the vertical bar between the two front windows is under 45 degrees and that the top line of all windows (eyebrows not counted) are in the same horizontal plane - if I am right. I cut them from a piece of carton and there's only 1 way to position windows 1 and 2 if you assume the 45 degree angle and the top line being in a horizontal plane. With higher math you could probably calculate angle a, b, e and f in the drawing of my thread starter above.

But I discovered something interesting on a photo on Ian's site. I made some notes on it and attached it here. Is it right to say that window 2 and 3 are in the same plane (hence: there's no angle between the two)?

Another approach is to know the width between the positions where the windows connect (see other attachment).

5. That's right, there is no angle between #2 & #3 windows. They are in the same plane.

6. Hi GoldOne

depends on the number of crashes the plane survived... The more crashes, the more angle.
(just joking)

Juan Cordon has some good pictures.

Michael by that logic wouldn't all the windows on a particular aircraft be considered in the same plane? If they were in another plane then I'd say the technicians confused which plane the windows were going to be installed in.

8. Gold,
The green line measurements (very rough) in your second post are;
Top L1 & R1= 141cm
Bottom = 157cm

Top L2 & R2 = 171cm
Bottom =209cm

Top L3 & R3 = 209cm
Bottom = 233cm
I cannot measure the angles. Hope this gets you closer.

Aughhhhhhhhhhh....

10. Euclidean geometry seems to do the trick. I'd have to study it but an expert calculated the angles for me. See picture. I take no responsibility tho
