By the way Creamie, there are a few ALA's in my area, not on the charts that occasionally get busy with fly ins. The last one I recall had over 40 aircraft present. If the clubbies elect to use 126.7 are they now breaking the law?
What
should happen, and what
used to happen when aviation was regulated competently and pilots were trained to a standard, was that the organisers of the fly in would arrange for the promulgation of a thing called a 'NOTAM' that pilots used to 'read' and 'comprehend' as part of their 'pre-flight planning' and 'operational decision-making', in which NOTAM the location of and discrete frequency for the activity could be specified.
Just do whatever Dick says is common sense. Nothing could possibly go wrong.
