Our club has a ''safety officer'' that will occasionally get involved with situations like this.
Normally if someone is flying by themselves, they can do whatever they want.
However once someone else takes off, everyone must fall into an established pattern.
We all try to look out for each other, and keep out of each others way. Everyone values this.
We get the occasional person who doesn't follow in.
Everyone else starts shouting ''the pattern is right to left'' or ''the pattern is left to right'' and the experienced members take great pains to declare their takeoffs and landings to hopefully demonstate HOW these erratic flyers are expected to behave.
However if the hints are not taken, the safety officer is alerted, and our members are somewhat vocal about enforcing some basic good practices.
Usually it only rarely gets as far as the last steps, as leadership by example tends to work very well, especially when everyone else is doing it.
This sounds like my old club too. Today I fly off a dry lake bed so there is no club or any real rules. Over time you learn who is safe to fly with and who isn't. Every once in a while a group of guys come out with there hot rod planes and start flying. We just let them have the sky and wait for them to land before we go up again. I know I have mentioned to them to please stay grounded while I was flying and several of the other regular pilots have done the same thing. We give them the sky and they do the same for us. These are nice enough guys but have never flown at a real club with rules so they just don't understand things like the pattern. Most of the regulars don't really fly a pattern either, most of us are stunt pilots so it's hard to fly a pattern while doing a flat spin, we do know each other though so I feel safer in the air with some people then I do with others. Talk to the club safety officer and bring it up at the club meeting.
