F contour — Lower Deck Contour Limits

Lower deck full-width angled (LD-6/LD-8). Public letter summary only; ULDR drawings are paywalled and are not copied.

Industry label: F
IATA contour letter: F
Deck: Lower Deck
Maximum height: 162.6 cm / 64 in
Base width: 406.4 cm / 160 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.

F section, 162.6 cm tall on a 406.4 cm published width. Rectangle only; no taper is inferred.
Height above floor	Maximum width	Taper
0 cm / 0 in	406.4 cm / 160 in	full published width
162.6 cm / 64 in	406.4 cm / 160 in	full published width

Verification status

Aircraft

Positions accepting this contour are recorded on: A300-600, A310, B747-400F, B747-8, B747F, B767-200, B767-300, B767-300F, B767-400ER, B777-200, B777-200LR, B777-300ER, B777F, B787-10, B787-8, B787-9. 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 F contourThe build-up guide takes the pallet step by step so each layer is checked against the contour before release.
