Field layout appears to be an AMA sacred cow that needs revisited. Flight operations parallel to the pits are a bad idea. No # of fences no matter how high will stop planes diving from the sky. Our field has operated for 35 years using a system of setting up the pits so that all flight operations, take off and landings, are into the wind and away from the flight line. We have a square well mowed 5 acre field and determine a pit line by parking our vehicles in a row on the whichever side of the field allows us to take off and land into the wind. If the wind is out of the southwest we park on the east side of the field and take off to the southwest away from pit row, and land from the the northeast into the southwest wind This gets the plane headed away from the pit area on take off, and going away from the pits on landing. On a day with a northeast wind we would park on the south or west side and reverse the directions. On calm days we often park on the east side in the am and in late afternoon move all the vehicles and planes to the west side of the field so the sun is at our backs all day! Panes must be started facing away from the pits and held by a restrainer when started. Taxing is allowed to within 20 feet of the flight line. Our field is well drained and usually firm enough to drive on except for a few days in early spring. We set up planes and equipment directly out of the back of our vehicles and drive only on the outside edge of the field. We have never had a serious accident in 35 years using this method and cases of landings into the end of the flight line on crosswind days is non existent for us. Most AMA field layouts seem to protect for planes "loose" on the ground, the serious injuries seem to be from planes coming from flying altitude down into someone. The man just injured this week end was in his tent! How much are one, two , or even 3 fences 3 feet high, and standing in "pilot stations" really going to protect us?
