PLA Envelope — Lower Deck Contour Limits

An internal working envelope for 60 in wide lower-deck pallets. “PLD” does not appear in the IATA code list, and a rectangle running full height contradicts the lower-deck curvature, so this is labelled an approximation.

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.

Verification status

Aircraft

Positions accepting this contour are recorded on: B747, B777, B767, B787, A330, A350. 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.
