Payload Connector is the official blog of the Regional Air Cargo Carriers Association (RACCA) which has 56 member companies. RACCA represents and serves the interests our member Part 135 and Part 121 cargo carriers in the United States. The typical mission for these aircraft is to retrieve packages and other cargo from smaller communities and deliver that payload to connecting air cargo ports to be loaded aboard a larger aircraft for a longer flight to a sort center. Afterward, that process is reversed as cargo is then offloaded from a large freighter arriving before dawn from the sort center, to another of our members’ airplanes for delivery early in the morning to its ultimate destination, often a smaller community.
