How is an air cargo terminal different from a regular warehouse?

From the outside, an air cargo terminal looks like a large warehouse with many doors. But what drives the design are constraints that ordinary warehouses do not have.

Two sides, two control modes

A cargo terminal always has a landside and an airside, separated by a security boundary. Every flow of people, cargo and vehicles must be clearly assigned to one side, and every point that crosses the boundary is a control point that needs space. Ordinary warehouses have no such constraint, so a warehouse layout cannot simply be transplanted.

Cargo moves in unit load devices, not standard pallets

Air cargo moves in specialized unit load devices — air cargo pallets and containers have their own sizes and shapes, some with contoured profiles to fit the aircraft fuselage cross-section. Clear height, door size, floor load and maneuvering radius must all be calculated for these units, not for standard warehouse pallets.

Handling equipment must be accommodated from the structural design stage

Conveyor systems, roller tables, lifts and unit load device storage racks need their positions, openings and local loads worked out from the design stage. This is where problems most often arise when the building and the equipment are delivered by two different contractors whose schedules and documents do not match. In cargo terminal projects, supervision of equipment installation is therefore as important as construction supervision.

Special cargo needs dedicated areas

Dangerous goods, high-value cargo, perishables and cold-chain cargo each have their own requirements for storage areas, ventilation, access control and fire protection. The space for these areas is often underestimated at the investment project stage and later has to be taken out of the general operating area.

Equipment parking and service vehicle routes

The airside also needs parking for tugs, unit load device loaders and other ground support equipment. This area produces no throughput, so it is easily cut from the drawings, but without it parked equipment spills onto operating routes and reduces the terminal's own throughput capacity.
