What is a ULD?

Unit Load Device (ULD) is a pallet or container used to load luggage, freight, and mail on aircraft. ULDs allow large quantities of cargo to be bundled into single units, improving loading efficiency and protecting goods during transport.

ULDs come in various sizes to fit different aircraft types and deck positions. Lower deck containers (LD) are designed to fit in the cargo holds of wide-body aircraft, while main deck pallets are used on freighters.

Container vs Pallet

Containers

Enclosed structure with rigid walls. Better protection, no netting required. Higher tare weight but better for loose cargo and sensitive goods.

Pallets

Flat platform requiring nets for restraint. Lower tare weight, more flexible for oversized items. Common on main deck of freighters.

Key Considerations
  • Aircraft Compatibility: Ensure ULD fits destination aircraft
  • Contour Fit: Use correct contour for deck position
  • Weight Distribution: Balance load within ULD
  • CG Position: Mark center of gravity for handling
Pro Tips
  • Use LD3s for smaller shipments - better availability on passenger flights
  • Build to full height for volume efficiency on main deck pallets
  • Consider ULD positioning fees when booking
  • Check airline-specific ULD policies and restrictions
  • Pre-book ULDs during peak seasons to ensure availability
Common Mistakes
  • Exceeding ULD weight limits - leads to rejection
  • Using wrong ULD type for aircraft configuration
  • Poor weight distribution causing handling issues
  • Not accounting for ULD tare weight in calculations
  • Forgetting to verify ULD availability at origin
