Our EAA chapter flies over several local parades each year. The parade marshals use us as the parade opener. So we practice on timing, as that is about all we can do. Staying at 1,000 AGL and, of course, nothing even close to aerobatics, just a single row fly by with at least a 1/4 mile between aircraft except we added a 3 plane formation pass by a team from the Beechnuts. They have really brought us great comments and made us more in demand. My question is where would I start if we wanted to get a pass to fly a little lower, say 600' or 800" AGL? Or don't even bother asking! Hoping one of you air shows types might chime in. By the way there is no absolutely money changing hands here what so ever, just a bunch of flying enthusiasts looking for another mission.
