AKH, also called LD3-45WF, is a contoured air-cargo unit, not a rectangular shipping container. Its usable interior, door opening and permitted gross weight must be checked for the actual operator and unit. A published volume alone cannot establish how many cartons will fit.
CBM3 status, reviewed 9 October 2026: the ANA AKH calculation profile is temporarily unavailable while its exact model and internal contour are reconciled with primary documents. This page is a dimensional reference and preparation checklist, not an available AKH fit calculation or loading approval. Earlier CBM3 results must not be treated as verified physical AKH capacity.
ANA AKH dimensions: what the current reference actually shows
The following figures are from the international AKH entry in ANA Cargo’s 2026 Dimension Guide, printed page 29. They describe that published entry, not every AKH unit. The internal sketch and external table use different measurement conventions.
| Published field | ANA reference value | Meaning for planning |
|---|---|---|
| Internal depth | 140 cm | Drawing dimension, not the external base dimension. |
| Upper internal span | 241 cm | The lower sides taper; this width is not available at every height. |
| Internal height / lower internal span | 113 cm / 143 cm | Do not turn these dimensions into a fully usable rectangular box. |
| Door opening | 137 x 105 cm | Separate from the interior and from the aircraft cargo door. |
| External dimensions, as tabulated | 156 x 153 x 114 cm | Not an internal loading envelope or the complete upper contour span. |
| Nominal internal volume | 3.3 m3 | Not a carton-capacity guarantee. |
| Tare / gross limit including the ULD | 95 kg / 1,134 kg | Check the actual unit and the operator’s applicable restrictions. |
Why AKH specifications differ between sources
An equipment code does not identify every manufacturing variant. For example, IAG Cargo lists an AKH with 3.4 m3 volume and 76 kg tare. Those are not replacement values for the ANA entry above. Similarly, a domestic-service entry must not be mixed with an international-service drawing just because both mention AKH.
Nordisk’s component-maintenance-manual index lists multiple ANA-associated AKH models and drawing references. That index helps identify the unit, but it is not the complete drawing of the interior space available to cargo. Use the manufacturer, part number, serial identification and applicable drawing revision together.
AKH payload: gross weight is not cargo allowance
Start with the permitted gross weight for the actual unit and flight position. Subtract the actual ULD tare and account for anything else included in gross mass, such as packaging and restraint materials. A nominal catalogue subtraction is not a certified payload for an individual shipment. The applicable aircraft-position limit may be more restrictive.
Keep individual package masses as well as the shipment total. A total below a mass limit does not demonstrate acceptable local floor loading, load distribution or restraint. These checks belong to the operator’s applicable loading procedures and the unit’s approved documentation.
How many cartons fit in an AKH?
There is no reliable universal carton count. You need carton outside dimensions, entered quantities, permitted orientations, stacking restrictions and the verified cargo-clear envelope of the assigned unit. The door, tapered sides and handling clearance can reject cargo even when its summed volume is below the nominal ULD volume.
- Measure the packed cargo, including protrusions and protective packaging.
- Record the quantity and gross mass per package, not only the total cubic volume.
- Keep upright-only and non-stackable restrictions explicit. Do not grant full 3D rotation just to improve a simulated count.
- Obtain the actual unit’s complete internal contour and clear opening dimensions.
- Have the operator confirm loading access, restraint, mass distribution and aircraft-position compatibility.
You can use the CBM3 cargo calculator to prepare a cargo list and review package volume and mass. Selecting another equipment profile, or entering AKH’s outer dimensions as Custom Size, does not produce an AKH fit check. The cargo spreadsheet guide explains how to organize import data; a spreadsheet is not an aircraft-loading approval.
Why the CBM3 AKH planner is paused
The previous software profile used an envelope that has not been reconciled with the current ANA internal drawing. The drawing also does not fully dimension the lower corner geometry needed to recreate the complete cargo-clear contour. Presenting the old profile as an exact engineering model would therefore be misleading.
Re-enabling the profile requires an identified manufacturer/model, a complete applicable internal drawing, verified door and mass constraints, and fresh boundary and placement checks. A type-code match, a manufacturer’s catalogue illustration or an AI-generated image cannot replace this evidence. No AKH loading result is offered on this page while that review remains open.
Questions before booking an AKH shipment
Is AKH the same as a standard LD3?
Do not substitute one for the other. Confirm the complete ULD designation and the operator’s actual unit rather than borrowing dimensions from a differently named LD3 profile.
Does passing through the ULD door prove the cargo can be loaded?
No. Door clearance is only one condition. The movement path, final contour, supporting surface, aircraft opening and operating restrictions still matter.
Can I use an older saved AKH plan?
Keep it as a historical planning record, not as proof of physical fit. Reconfirm the actual equipment and rerun a validated profile once the technical review has been completed.

How to inspect and hand over a loading plan
Use the selected plan and the complete shipment data. Recheck the result after changing cargo, equipment or handling rules.
See every cargo unit in context
Search the cargo inventory, focus on an item and switch between realistic, operational, top and side views. Inspect pallet layers and height sections.
The inventory separates requested units, units in the selected container, units in other containers and unplaced units. Select a row to find its cargo in the scene; playback and height sections show only part of the complete plan.
Use pallet details to inspect full, partial and mixed pallets. A height section filters the view; it does not remove cargo from the plan. Vehicle bodies and wheels provide visual context.
Prepare clearer warehouse instructions
Use product colors and short codes, named groups and delivery stops. Choose a summary or warehouse PDF for the selected plan.
Assign product colors and short codes to connect the cargo table, 3D view and reports. Group and stop names improve instructions; apply the appropriate loading rules when a sequence must be enforced.
Compare verified alternatives and review any manual moves. A manual reallocation affects the current preview and PDF; saved or shared inputs recalculate the automatic arrangement when reopened. Export again after changes.
Read the estimated center of gravity
Review longitudinal, lateral and height coordinates from known cargo and pallet masses. Check the displayed origin and units before comparing plans.
The estimate assumes each item's mass is centered and excludes vehicle tare. Missing or stale additional-material records can leave the complete-load assessment unavailable; explicitly declare none when no extra materials are present.
Coordinates use the load-space frame, not road height. For Step Deck, X starts at the raised front end and Y at the lower-deck datum; axle-form distances run from the rear toward the cab.
Distinguish the loading unit from its carrying vehicle
This loading unit alone does not define an axle configuration.
Inspect cargo and pallet weight distribution in this loading space. A container, swap body or air-cargo unit does not identify the road chassis, rail wagon or aircraft carrying it.
Axle estimates are available after selecting a supported complete road or rail vehicle. Enter its actual mounting positions, full empty reactions and applicable limits; do not reuse a trailer reference as container or aircraft approval.
