Where the taper starts

Profile is modelled as rectangular

Permitted width at height

Read as: at the stated height above the pallet or container floor, this is the maximum overall width the build may occupy. A load that exceeds any single row is out of contour, even if it is under the maximum height.

No base width was published for this letter, so no width-at-height section is drawn. A taper is not inferred.

Verification status

Aircraft

No aircraft assignment is claimed. Published sources did not confirm the per-position limits, and guessing them here would be worse than leaving the row empty.

ULDs built to M

No ULD in the library is assigned to M; the contour is documented for reference.

Work a build against the M contourThe build-up guide takes the pallet step by step so each layer is checked against the contour before release.
