Jump170pilot

Diverdriver.com was a good resource for me when I started as well. We always brief our pilots on what to do if someone's bag starts to come out on the step. Also, the causes of engine failures (fuel exhaustion). After a while they'll get a spidey sense of when someone bumps the fuel selector in the 182. They need to know when to let jumpers get out of the plane in an emergency and when to keep them in.

Don't rush them. As a former jump pilot and current jumper I understand the urge to get to altitude fast. I hate sitting in the Cessna. That being said, mistakes happen when pilots rush. If they're a decent pilot they will start turning loads quickly within a couple dozen loads after things become second nature. If they have a wet commercial ticket this is a totally new kind of flying for them. Especially on descent, do not rush.
