At our field helis and fixed wings peacefully co-exist. Those learning/practicing hovering do so in an area that's past the pits and off the runway. Those doing extreme aerobatics usually get the air to themselves, while the rest of us watch in amazement, and those just flying around get the space over the runway, but stay high enough that someone landing, planned or because of a deadstick, can do so without risk of collision. The field is informally reserved for helis every Sunday morning. Technically, those of us with fixed wing planes could fly at that time, but we give the helis their space. I feel bad when I see reports of conflicts. Reminds me how lucky I am to live so close to such a great club.
