SD,
The one that we always try to do at our club, especially when the flight line is buzzing is to loudly announce your intention to either take off or land. If someone sees someone taking off while someone is landing they will usually yell out ' Bob is landing' (everyone in the club is named Bob
) to help prevent a mishap on the ground.
One other peeve that we have is when someone is taking off and for some reason they will head towards the flight line and continue their take off run which will usually result in flying past the flight line into the no-fly area. We will usually reinforce the idea that it is OK to stop your take off run and reset yourself to get a nice takeoff down the middle of the runway.
We never yell, just quietly go over when Bob
is done flying and remind him about safety at the field. Bob usually knows when he does bad so he usually yells out ' Sorry, I should have canned that take off run!"
