LD-11 (ALP) Air ULD dimensions
An LD-11 (ALP) Air ULD measures 3.12 m (10′3″) long, 1.47 m (4′10″) wide and 1.57 m (5′2″) high inside — about 7.2 m³ (255 ft³) of usable space, with a maximum gross weight up to 3,176 kg (7,002 lb).
IATA LD-11 (ALP) — a full-width, rectangular lower-deck container on a 3175mm bay length, used in the 747/777/787/MD-11 lower hold. Unlike the contoured LD-3 and LD-7, its walls are square, so the usable space is a plain box: about 7.2m³ inside a 3175 × 1534 × 1626mm shell.
IATA figures: the weight column is maximum GROSS weight (tare included) and the volume is the IATA rated envelope. ContainerMath models the contoured shell conservatively, so a real plan fills slightly less.
Internal dimensions and capacity
| Specification | Metric | Imperial |
|---|---|---|
| Internal length | 3.12 m | 10′3″ (10.2 ft) |
| Internal width | 1.47 m | 4′10″ |
| Internal height | 1.57 m | 5′2″ |
| Capacity | 7.2 m³ | 255 ft³ |
| Floor area | 4.6 m² | 50 ft² |
| Max gross weight | 3,176 kg | 7,002 lb |
Internal (usable) figures, not external. Capacity is the geometric interior volume — real cargo never fills 100% of it, because pallets, dunnage and irregular shapes leave void space.
How much of this air cargo uld will your cargo fill?
The table above is the box. What matters is how your cargo sits in it — how many units fit, where the weight lands, and whether you run out of floor or payload first. Enter your cargo and get the answer, free and without signing up.
