The 767 Freighter is equipped with powered cargo-handling equipment, both on the main deck and in lower holds. The cargo-handling system provides complete automation of the cargo-loading process, with the operator's interface through control panels and joysticks. The freighter's main deck has both interior and exterior master control panels as well as local control panels to provide maximum flexibility.
The cargo-handling system's power-drive units move the cargo containers into and out of the airplane and are equipped with high-tech sensors. The sensor information is fed back to the system's microprocessor-based controllers, which move only the power-drive units necessary to load each container, preventing wear and tear on the equipment and improving reliability. Another advantage is that the power-drive units weigh less than those used on previous airplanes.
A unique feature of the cargo-handling system is the extensive use of built-in test equipment, or BITE, which allows troubleshooting in the event of a system problem. This function not only detects and isolates controller faults; it also provides the maintenance operator with a series of automated tests to isolate other system faults.
Environmental control system changes make the airplane suitable for transporting live animals and perishable goods. Plenty of fresh air is delivered to the cargo areas, and temperatures can be controlled to cool or heat the freight appropriately.
