A 294.6 cm (116 in) main-deck contour. The IATA letter for the 116 in envelope is established, but the mapping of that letter to the industry label “Q4” is not, and the taper points below are approximations.
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.
| Height above floor | Maximum width | Taper |
|---|---|---|
| 0 cm / 0 in | 243.8 cm / 96 in | full base width |
| 240 cm / 94.5 in | 243.8 cm / 96 in | full base width |
| 260 cm / 102.4 in | 222 cm / 87.4 in | −21.8 cm (8.6 in) narrower |
| 280 cm / 110.2 in | 194 cm / 76.4 in | −49.8 cm (19.6 in) narrower |
| 294.6 cm / 116 in | 158 cm / 62.2 in | −85.8 cm (33.8 in) narrower |
Positions accepting this contour are recorded on: B747F, B777F. 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 747-8F | Freighter | 33 positions · 317.5 cm wide | 32 positions · 162.6 cm limit |
| Boeing 777F | Freighter | 27 positions · 317.5 cm wide | 28 positions · 162.6 cm limit |
