I flew jumpers last summer and had a blast. It gets repetitive, but it is good experience. Max gross take off. Fly a precise profile to altitude. High speed descent, and (for me at least) a crosswind landing.
The pilots parachute is there incase one of the jumpers chutes deploys while in the door. It could (and has) wrapped around the tail. This could render the airplane uncontrollable. Soultion: please exit through the nearest exit.
My experiance was espesialy fun since it the DZ had it's own grass strip. Also the 67 (?) model C-182 only had a fuel line pick up in the rear of the tank. This causes the fuel lines to run dry during a steep descent. The first time this happened my heart went into my throat, after the 10th time I didn't even blink. I just continued my descent and made a power off landing, restarted the engine and taxied to the fuel pumps. Yes I did take off with enough fuel to make my intended flight with a 30 minute reserve, I just had to shake it around to use it.
Jumpers are a cool bunch. Not all there, but what do you expect. I intended to do a tandem, but never got around to it.
One last thing, DO NOT let anyone convince you to take off in an overloaded aircraft. The C-182 was only ever designed to carry 4 adults. Removeing the seats and some fuel allows an extra person to be cramed in, but just barely. One of the pilots at the DZ where I worked said he had no problem carrying five big guys, I said thanks, but no thanks. I don't need flight time bad enough to have an accident on my record, or be in the hospital.
