Yes valid rules everywhere uncontrolled , but as always the catch is in the details :
the remark " unless otherwise indicated"
But indicated where ? in the approach chart is there is one of course, or the AIP supplement or , if not listed ( private), the airport operator website ?
Most small airfields /aeroclub strips have noise abatement constraints nowadays and ask not to overfly certain areas , which will be all patterns South or North , which will mean right turns in one runway direction .
