Actually GASAX we do provde AG as I put in my last post. Because the strip is just one day a year and a very public event we do all we can to mitigate against all risks, and the pilots' guide is a single A4 sheet with a colour aerial photograph with circuit direction, avoid areas etc on it. I don't use slot times so that visitors can fit the flight into their day as they see fit, BUT our insurers insist that we must know as much as possible about visiting aircraft and that we brief visiting pilots about the site as thoroughly as possible.
PPR is not there to deny anyone the freedom to fly, it is mainly there for the safety of all concerned.
