Air Cargo ULD Reference and Build-Up Checking

Container and pallet dimensions, contour envelopes by deck, aircraft hold layouts and chargeable weight — in one place, with the source and verification status of every figure.

Built for the two people who actually need this at 03:00: the build-up operative deciding whether a load clears the contour, and the planner deciding what the hold will take. No sign-up to look anything up.

Reference

What	Coverage
ULD dimensions and weights	15 container and pallet types, cm and inches
Contour limits	11 sections, height and permitted width at each level
Aircraft holds	10 airframes, positions, door heights, accepted contours
Calculators	Chargeable weight, CBM, volume weight, centre of gravity

Checking a build

The simulator places cartons on a pallet or in a container, applies the contour for the deck you chose, and flags what breaks the envelope — in a 2D section and in 3D. Booking lists parse from Excel, CSV or PDF in your browser, with volume and chargeable weight computed locally.

How the data was assembled

Parameters cross-checked against published carrier specifications (Cathay Pacific W&B, ANA Cargo, China Airlines Cargo, DSV) and ground-handler manuals.
Where two bases coexist — structural versus operational max gross, declared volume versus contour envelope — both are shown rather than one silently chosen.
Contour letters traceable to the IATA letter table are marked as such; Q-number mappings that could not be confirmed are labelled unverified.
Revision history is published in the repository, so a corrected figure can be traced to the date and source that changed it.
