"loadmaster"
We mostly work with b3's and and a old military huey, the loadmaster is just the fancy name of the guy responsible for getting the right equipment and right amount of fuel along for the job and beeing the company rep on the ground, making sure the groundwork is beeing done like we want it to be done (when it involves the helo). Maybe you got another definition of the name, but that's what I do anyway =)
best regards
