LD9 Contour — Lower Deck Contour Limits

A 223.5 cm wide lower-deck section. Both shoulders are cut, so the practical limit is the door profile of the specific hold.

Industry label: LD9
IATA contour letter: Not establishedNo IATA letter could be matched to this label in published sources.
Deck: Lower Deck
Maximum height: 162.6 cm / 64 in
Base width: 223.5 cm / 88 in
Base length: 317.5 cm / 125 in
Where the taper starts: 100 cm / 39.4 inFull width is carried up to 100 cm, then the section narrows toward the top.

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.

LD9 section, 162.6 cm tall on a 223.5 × 317.5 cm base.
Height above floor	Maximum width	Taper
0 cm / 0 in	223.5 cm / 88 in	full base width
100 cm / 39.4 in	223.5 cm / 88 in	full base width
140 cm / 55.1 in	210 cm / 82.7 in	−13.5 cm (5.3 in) narrower
162.6 cm / 64 in	180 cm / 70.9 in	−43.5 cm (17.1 in) narrower

Verification status

Aircraft

Positions accepting this contour are recorded on: B747, B777, B767, B787. 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.

Aircraft	Type	Main deck	Lower deck
Boeing 747 (passenger)	Wide-body passenger	No cargo position	30 positions · 162.6 cm limit
Boeing 777 (passenger)	Wide-body passenger	No cargo position	14 positions · 162.6 cm limit
Boeing 767 (passenger)	Wide-body passenger	No cargo position	9 positions · 162.6 cm limit
Boeing 787	Wide-body passenger	No cargo position	16 positions · 162.6 cm limit
