Huh, I stand corrected. I checked and our AMM says the same (obviously).
I was referencing the Weight and Balance Control and Loading Manual, which has a diagram and the below table on one of the later pages:
ITEM WEIGHT B.A.
NO. BODY COMPONENTS LB/EA KG/EA IN.
1 Door 5 Main Entry Door (Left) 440 200 2261
2 Side Cargo Door 1952 885 1850
3 Door 1 Main Entry Door (Left) 452 205 464
4 Upper Deck Door 211 96 405
5 Emergency Exit Left Side (Not Shown) 22 10 370
6 No. 3 Windshield (Left & Right) 60 27 326
7 No. 2 Windshield (Left & Right) 45 20 306
8 No. 1 Windshield (Left & Right) 620 281 299
9 APU Exhaust Cone 100 45 2760
10 APU Access Door (2) 80 36 2699
11 Bulk Cargo Door 147 67 2006
12 Aft Cargo Door 742 337 1865
13 Aft Outbd Main Body Gear Doors (2) 18 8 1465
14 Aft Inbd Main Body Gear Doors (2) 103 47 1441
That's "No. 1 Windshield (Left & Right) 620 LB/each 281 KG/each 299 inches CG"
Perhaps I misread it and it's 281 KG for both the Left and Right
together, but that's still a significant difference from the AMM. I wonder why.
Sorry for the formatting. I don't have enough posts yet to be able to post pictures from an album.
