I hope they are viewed as being quality sticks! I have about 800 flying jumpers.
A retired airline captain first hired me to fly jumpers for him. I asked him the same question at some point. He basically said, "Airlines have hiring all wrong. They look at total time. Anybody can fly from here to there and log time. They should want a pilot who will fly 6-8 hours per day, make 15-30 takeoffs and landings, do it at max weight while eating a cheeseburger and talking to ATC, all the while trying not to get killed by the jumpers." That having been said, I agree with lookup.
From what I've seen on this board, you will get the inevitable responses to your question about not paying your dues and flight instruction is the only way to go. Flight instruction and flight instructors are wonderful. I have appreciated every CFI I've had and their knowledge. Likewise, they have appreciated my job flying jumpers, although they did think it was a little crazy. Heck, I thought they were crazy teaching VMC demos in a Baron.
Anyway, if you fly jumpers log your time as one entry for the entire day.
