H contour — Lower Deck Contour Limits

Lower deck low wide (45 in / LD3-45). Public letter summary only; ULDR drawings are paywalled and are not copied.

Industry label: H
IATA contour letter: H
Deck: Lower Deck
Maximum height: 114.3 cm / 45 in
Base width: 243.8 cm / 96 in
Base length: Not published
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.

H section, 114.3 cm tall on a 243.8 cm published width. Rectangle only; no taper is inferred.
Height above floor	Maximum width	Taper
0 cm / 0 in	243.8 cm / 96 in	full published width

Verification status

Aircraft

Positions accepting this contour are recorded on: A319, A320, A321. A main-deck contour is never a lower-deck limit — the same PMC that takes 116 in or 118 in on a freighter main deck is limited to about 64 in in a wide-body passenger belly.

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