Thanks to everyone that has posted on this thread, I have been interested in reading all of the posts from the experienced jumpers out there.
As a military helicopter pilot and someone who does a bit of private piloting I have a slightly different perspective to some of the other pilots that have posted. Sectionals are freely available to us and we have more rigid pre flight procedures. As I have sectionals I was therefore surprised that fewer private pilots are using them and it has made me think even more that something needs to be done to increase communication between skydivers and private pilots.
So here is my suggestion.
Every dropzone sends out an e-mail or fax to every airfield within a 100 mile radius. The dropzones could ask the airfield to display these notices on the NOTAM board with details of the DZ location, normal jumping procedures and times, monitored frequencies and contact details.
Granted this won't reach every private pilot but pilots talk to each other and this information would soon spread.
I also acknowledge that good spotting is very important and we should never just rely on one spotter but encourage the entire load to look for aircraft.
If the USPA got on board with this as part of the annual safety day then I feel we could reduce the amount of private pilots flying over dropzones unaware that they are even there.
As a pilot I don't want anyone falling through my rotor or wing any more than I want to fall through one while I'm jumping.
