RE: Taxiing in the pitts...
It's hard to understand your situation with out pictures of the layout. At our field we have a 4' fence between the pit area and the flight stations. Plane are started at the flight stations only. No plane is allowed to be started on the other side of the fence. As a CD I wouldn't allow planes to be started in the pit area only at the flight stations. No one would be allowed to carry a plane that is running at all period. The pit area to for set up and parking the planes. Start the planes at the flight stations and taxi on to the runway. Dennis
